+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events
+
+### What is the IVOA?
+
+The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to "facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems, and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory."
+The IVOA now comprises 16 VO projects from Armenia, Australia, Canada, China,
+Europe, France, Germany, Hungary, India, Italy, Japan, Korea, Russia, Spain, the
+United Kingdom, and the United States. Membership is open to other national and
+international projects according to the IVOA Guidelines for Participation. You
+can read more about the IVOA and what we do at .
+
+# VO applications highlights
+
+### AstroGrid VO Desktop Suite
+
+{{< side-image image="astrogrid_sh_thumb.jpg" >}}
+
+This newly released suite includes several interlinked tools including an
+iTunes-inspired browser, VOExplorer, which allows you to search, filter, save
+and bookmark your favourite VO resources. You can search for data by position,
+or run more complex queries where available. AstroRuntime software runs in the
+background and allows seamless visualization of selected catalogues, images,
+spectra, and time domain datasets in VO enabled tools. You can also save and
+share files in VOSpace and invoke remote applications. For those wanting
+command-line access, all the functionality of the VODesktop is available using
+python scripting, with IDL to follow.
+
+**More information:**
+
+{{}}
+
+### VirGO v1.3.1
+
+{{< side-image image="VirGOLogo.png" >}}
+
+VirGO is the next generation visual browser for the ESO Science Archive
+Facility. VirGO provides an easy access to millions of raw frames in a visual
+and intuitive way. Its main feature is the performance of real-time access and
+graphical display of a large number of observations by showing instrumental
+footprints and image previews, and the selection and filtering for subsequent
+retrieval. It uses the DSS as background images and allows the user to view the
+sky in a "real-life mode" as seen from the main ESO sites. Data interfaces are
+based on VO standards, enabling access to images and spectra hosted by other
+data centers. VirGO can also exchange data with other VO applications through
+the PLASTIC messaging system. A large fraction of ESO's non proprietary science
+products are already accessible through VirGO and more are to come, including
+the data products from the ESO Public Surveys.
+
+**More information:**
+
+{{}}
+
+### VO-CLI - Command Line Tools for the VO
+
+{{< side-image image="m33_vocli.png" >}}
+
+VO-CLI is a package of command-line tools that provides familiar unix-like
+access to VO services while hiding much of the complexity of the underlying VO
+framework from novice users. These tools can be used from the desktop, in
+various scripting environments, or in back-end CGI scripting to support web
+applications, and have the ability to output results in a variety of formats.
+Another key feature of the package is the ability to optionally use "common"
+names for both objects and VO resources; these names are resolved internally to
+sky positions or service URLs. "Power users" will quickly become proficient
+using the command-line interface; a web interface to the tasks is also available
+for novice users or those wishing to experiment.
+

+
+
+### Large Images in Aladin
+
+{{< side-image image="aladin_small.jpg" >}}
+
+The latest version of the Aladin software provided by CDS in Strasbourg now
+supports use of large images, unlimited by the local computer memory. Other
+changes include image transparency, automatic scale and orientation adjustment,
+Russian & traditional Chinese translation, and more. Aladin is an interactive
+software sky atlas allowing the user to visualize digitized astronomical images,
+superimpose entries from astronomical catalogues or databases, and interactively
+access related data and information from the Simbad database, the VizieR service
+and other archives for all known sources in the field

+### US-VO Data Discovery Website
+
+{{< side-image image="usvo_newwebsite.jpg" >}}
+
+The US National Virtual Observatory web page has been redesigned and has new
+links to a number of astronomer-friendly tools for data discovery and
+exploration. The new home page has a simplified design and a set of icons that
+we hope will help users identify frequently used tools and understand how the
+tools can be used together. There is a link to the NVO book, which is based on
+the NVO Summer Schools and gives extensive background on VO services and how to
+use them. Improved on-line help facilities with numerous examples and science
+use cases are also available. A new Discovery Wizard can help you determine
+which tools are most useful for your particular research needs.

+### VisIVO Server: Huge Data Exploration
+
+{{< side-image image="simVisiVO.jpg" thumbnail="simVisiVO_thumb.jpg" >}}
+
+VisIVO is a suite of tools specifically designed for the Virtual Observatory
+environment. VisIVO is made of three main tools: VisiVO Desktop, a standalone
+application for interactive data exploration, VisIVO Server, and VisIVO Web, a
+web portal for data manipulation using VisIVO Server. VisIVO Server is a
+command-line application for intuitive data exploration with 3D views being
+created from data tables. Its defining characteristic is support for very large
+data sizes with no fixed limit on dimensions. A grid version was recently
+deployed in the Cometa Consortium computational grid.
+
+**More information:**
+
+{{}}
+
+### VOPlatform
+
+{{< side-image image="VOPlatform-1.png" thumbnail="VOPlatform_thumb.png" >}}
+
+VOPlatform is a tool that provides users with an environment in which to place
+their frequently used VO tools and datasets, along with other resources such as
+documents, web links etc. The application has been developed in Java, and acts
+on data available in the VO Standard VOTable format. To launch a tool from
+within VOPlatform, it must be PLASTIC or SAMP compatible. VOPlatform supports
+drag-and-drop functionality and personalized bookmarks.
+
+**More information:**
+
+{{}}
+
+### TOPCAT: Does what you want with tables
+
+{{< side-image image="topcat.gif" thumbnail="topcat_thumb.gif" >}}
+
+TOPCAT is an easy to use but powerful GUI tool for all kinds of analysis and
+manipulation of tabular data, especially source catalogues. It has very flexible
+capabilities for plotting, calculation, selection, and crossmatching, amongst
+other things. It can read and write data in VO-standard formats (VOTable) as
+well as old favourites such as FITS and CSV. TOPCAT provides access to remote
+services and other desktop applications using VO standard protocols as well as
+being suitable for standalone use on local data. Operations are fast, and tables
+with few or many columns - up to around a million rows - are easily handled. A
+pure Java implementation makes it easy to install and robust to run. The
+companion package STILTS provides command-line access to the same facilities.
+TOPCAT is currently developed within the UK's AstroGrid project.

+
+### JVO On-Line Mosaicing Service for the SUBARU SuprimeCAM Images
+
+{{< side-image image="jvo.png" thumbnail="jvo_thumb.png" >}}
+
+The SUBARU telescope is located in Mauna Kea, Hawaii, and is operated by the
+National Astronomical Observatory of Japan (NAOJ). The SuprimeCAM is a
+wide-field (~ 30’ x 30’) optical camera, and about 10 TBytes of raw image data
+has already been archived. The Japanese Virtual Observatory (JVO) opened access
+to the SUBARU SuprimeCAM Images archive in March 2008. JVO also provides an
+on-line data reduction (flat, bias, distortion correction, astrometry) and
+mosaicing service for the SuprimeCAM images. It is recommended to obtain an
+account with the service, but guest users may enjoy the services.

+
+
+### VOSpec version 5.0
+
+{{< side-image image="VOSpecV5.0.jpg" thumbnail="VOSpecV5.0_thumb.jpg" >}}
+
+VOSpec is a multi-wavelength spectral analysis tool with access to spectra,
+theoretical models, and atomic and molecular line databases registered in the
+VO. The standard tools of VOSpec include line and continuum fitting, redshift
+and reddening correction, spectral arithmetic, and convolution between spectra
+and equivalent width calculations. The newly released version 5.0 improves the
+spectra handling capabilities, offering tree and table display modes, and offers
+organising functionalities according to the available metadata, including
+distance from the observation position. This version also updates the registry
+interface using the new Euro-VO registry and includes the functionality of
+adding a local registry. Finally, a new e-support portal is available where
+users can submit tickets and receive technical support from the ESA-VO Team.

+The very large and increasing number of quasars reckoned from various sky
+surveys leads to a large quantity of data which brings various and inhomogeneous
+information in the fields of astrometry, photometry, radioastronomy and
+spectroscopy. In this paper, we describe our work that aims to make available a
+general compilation of the largest number of recorded quasars obtained from all
+the available catalogues, with their best position estimates, and providing
+physical information at both optical and radio wavelengths.

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events
+
+---
+
+# VO applications highlights
+
+### VO Interoperability in DS9
+
+{{< side-image image="saoimage_thumb.jpg" >}}
+
+SAOImage DS9 is a standalone astronomical imaging and data visualization
+application. DS9 supports FITS images and binary tables, multiple frame buffers,
+region manipulation, and many scale algorithms and colormaps. It provides for
+easy communication with external analysis tasks and is highly configurable and
+extensible via messaging capabilities XPA, and the VO messaging protocol SAMP.
+Versions of DS9 currently exist for Linux, MacOSX, and Windows. DS9 supports
+advanced features such as multiple frame buffers, mosaic images, tiling,
+blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom,
+rotation, pan, and a variety of coordinate systems.

+
+### SPLAT-VO: Spectral Analysis Tool
+
+{{< side-image image="splat_ivoa_news.png" thumbnail="splat_ivoa_news_thumb.png" >}}
+
+SPLAT-VO is a spectral analysis tool that has been integrated into the VO. It
+can display, compare, modify, and analyze astronomical spectra stored in a
+number of formats, including FITS images, tables, and simple text files. It has
+full support for spectral coordinate systems in wavelength, frequency, energy,
+and velocity, and also for standard flux data units. SPLAT-VO can also convert
+coordinates between various frames of rest, topocentric, heliocentric etc. and
+has support for sub-millimetre sideband coordinate systems. Integration with the
+VO is fully supported for spectra stored in remote servers and communication has
+been updated to work with any VO-enabled tools.
+

+
+### VirGO - New capabilities for browsing VO resources and more
+
+{{< side-image image="virgo144.png" thumbnail="virgo144_thumb.png" >}}
+
+VirGO 1.4.4 presents new functions and capabilities enabling astronomers to take
+advantage of the power offered by the standards of the VO. VirGO now comes with
+access to VO resources from ESO and external data centres like the Hubble Space
+Telescope archive, the Canadian Astronomical Data Centre, the European Space
+agency archive and others. A new configuration panel allows users to easily
+enable, disable, and add resources in one click. Connections to other VO tools
+are now done with the VO messaging protocol SAMP, the user interface has been
+refined to make it more intuitive and faster, and VirGO can now also operate
+behind network proxies if required. A user guide will help you get started, and
+includes a detailed description of the user interface, and example use cases.

+
+### ATPy - VOTables in python
+
+{{< side-image image="atpy_logo_thumb.png" >}}
+
+Astronomical Tables in Python (ATpy) is a Python module that allows users to
+read, edit, convert, and save data in VOTable, FITS table, IPAC table, and SQL
+database formats. ATpy makes use of existing python modules to simplify the
+process of using and storing table data in a format-independent way. This makes
+sharing the data with others convenient and straightforward, and will help the
+widespread adoption of the VOTable format. The developers are always looking for
+feedback from users. Contact the developers via the
+[ATpy forums](http://sourceforge.net/apps/phpbb/atpy/) or by
+[emailing](mailto:astropython@gmail.com) them.

+
+### Your databases in the VO with Saada
+
+
+{{< side-image image="saada_news.png" thumbnail="saada_news_thumb.png" >}}
+
+Saada helps you to build databases for astronomy data. With Saada, databases may
+be created, managed, and deployed without the need to write code. Saada
+databases can mix data of different categories (spectra, images, catalogues,
+etc.) in multiple collections, and they come with a rich web interface and with
+native VO services making the publication of images, catalogues, and spectra
+into the VO very easy. Data stored in Saada databases can be linked each to
+other with persistent links to assist data browsing, and for data mining
+queries.

+### Skyalert.org
+
+{{< side-image image="skyalert.png" >}}
+
+[Skyalert](http://www.skyalert.org) is a web site that gives access to many
+streams of astronomical events. Recently active feeds include
+[SWIFT](http://heasarc.gsfc.nasa.gov/docs/swift/swiftsc.html) and Fermi, the
+[Catalina Realtime Transient survey](http://crts.caltech.edu),
+[GALEX](http://www.galex.caltech.edu/), microlensing events from MOA, newly
+discovered asteroids from the [CSS](http://www.lpl.arizona.edu/css/) survey,
+ultra-high energy events from [VERITAS](http://veritas.sao.arizona.edu/), and
+others. Skyalert attaches multi-sourced data to an astronomical event: VO data
+services (including [SIMBAD](http://simbad.u-strasbg.fr) and
+[NED](http://nedwww.ipac.caltech.edu/)) are automatically consulted and links to
+[Microsoft WorldWide Telescope](http://www.worldwidetelescope.org/),
+[SDSS](http://www.sdss.org/), and other external sites are built. Events can
+also trigger data mining code. Skyalert provides real-time feeds of breaking
+events that can be mashed up with free cloud tools, such as from
+[Google](http://feedburner.google.com/) and [Yahoo](http://pipes.yahoo.com/), to
+build new feeds. We are looking for new event streams, and for new ways to
+utilize feeds.

+VOSED is a tool developed in the framework of the Spanish VO to ease the
+generation of Spectral Energy Distributions (SEDs) by gathering information from
+the spectroscopic services available in the VO. These datasets can be
+complemented with photometric information from a number of Vizier catalogues as
+well as with data provided by the user. The SEDs are provided in VOTable format
+and can be uploaded in other VO tools (for instance,
+[VOSpec](http://www.sciops.esa.int/index.php?project=ESAVO&page=vospec)) for
+further visualisation and analysis.

+[A Population of Compact Elliptical Galaxies Detected with the Virtual Observatory.](http://arxiv.org/abs/0910.0293) Chilingarian et al. (2009) Science v.326 p.1379
+
+Chilingarian et al. report their discovery of 21 compact elliptical galaxies
+with the Virtual Observatory. These galaxies, characterized by small sizes and
+high stellar densities, are thought to form through tidal stripping of massive
+progenitors. Only a handful of such galaxies were previously known, preventing
+understanding of the role played by this mechanism in galaxy evolution. The new
+objects were uncovered via data mining using high-resolution images and large
+databases, and were followed-up with spectroscopic observations and numerical
+simulations. This work shows that all the galaxies exhibit old metal-rich
+stellar populations different from those of dwarf elliptical galaxies of similar
+masses but similar to those of more massive early-type galaxies, supporting the
+tidal stripping scenario.

+**The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 18 VO programs from Armenia, Australia, Brazil, Canada,
+China, Europe, France, Germany, Hungary, India, Italy, Japan, Russia, Spain, the
+United Kingdom, and the United States and inter-governmental organizations (ESA
+and ESO). Membership is open to other national and international programs
+according to the IVOA Guidelines for Participation. You can read more about the
+IVOA and what we do at .**
+
+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### IVOA Science Priorities
+
+The IVOA recognizes the importance of placing useful VO services and tools in
+the hands of astronomers. The mission of the IVOA Committee on Science
+Priorities (CSP) is to identify the research needs of the worldwide astronomy
+community that can benefit from VO related tools and services, and to assist in
+placing such tools and services into the research community. This committee is
+responsible for special science sessions at IVOA meetings, for identifying
+essential science capabilities that will affect IVOA activities, for ensuring
+coordination among IVOA Working Groups and Interest Groups in quickly
+establishing standards for such capabilities, and for fostering
+cross-communication among the astronomy communities and participating VO
+projects of the IVOA. Further details about the CSP and its activities can be
+found on the
+[IVOA website](https://wiki.ivoa.net/twiki/bin/view/IVOA/IvoaSciencePriorities).
+Comments and suggestions about the CSP are most welcome; please contact the
+chair of the CSP (Dave De Young), with your thoughts and ideas. Image

+
+### CDS Portal
+
+
+The newly released CDS Portal provides simultaneous access to the CDS services
+SIMBAD, Aladin, and VizieR through a unique web interface. Searching by
+astronomical source name or position returns integrated results of object
+identifiers, images, and catalogues. Results from SIMBAD or VizieR can be saved
+in the personal storage space provided, and lists of sky coordinates may be
+uploaded as VOTables (as input to queries).

+
+### SAMPy: a Python Module for SAMP Messaging
+
+SAMPy is a Python module developed by the PANDORA group of the Italian VO. SAMPy
+allows Python scripts to communicate with existing VO applications (i.e. TOPCAT,
+Aladin, VOSpec, DS9) on one side, and with Python libraries on the other side.
+With SAMPy, images or tables may be viewed with VO tools via the Python console
+(or a Python script) and then analysed using existing Python libraries such as
+SciPy or NumPy, or other specific astronomical software from the AstroPython or
+AstroPy portals.

+
+### VOSA: VO SED Analyzer
+
+VOSA is a tool developed by the Spanish VO designed to determine physical
+parameters of astronomical objects through the comparison of observed photometry
+gathered from VO services with synthetic photometry obtained from different
+collections of theoretical models.

+### WebSampConnector - Stay tuned in to the VO!
+
+WebSampConnector is a client toolkit that enables web-based astronomy services
+to interoperate and communicate with VO applications: no more save and load, or
+cut and paste in the VO world! WebSampConnector allows you to broadcast your
+favorite VOTable or spectrum into VO applications connected to a SAMP hub. It
+makes it possible to send sky coordinates or a set of table rows from VO
+software directly into a Web page.
+[Try the demo](http://vo.imcce.fr/webservices/wsc/?demo). WebSampConnector is
+open source software which has been designed and developed by the
+[VO-Paris team](http://vo.obspm.fr/) and the
+[SAI OCL developers team](http://ocl.sai.msu.ru/). WebSampConnector is fully
+functional with Firefox and Internet Explorer on Linux and Windows platforms.

+
+### Featured Paper
+
+[Revisiting the Scale Length-μ0 Plane and the Freeman Law in the Local Universe](http://adsabs.harvard.edu/abs/2010arXiv1009.2692F), K. Fathi, ApJ, 722, 120 (2010)
+
+This paper explores the Freeman Law for an unprecedented large sample of 30000
+disk galaxies, selected and retrieved using VO technologies. Up to now, all
+observational statements related to the Freeman Law were based on a few tens of
+galaxies. The present study is the first based on a sample large enough to yield
+a statistically conclusive result out to z=0.3. This robust result is a leap
+forward in establishing the Freeman Law, and provides a test bed for numerical
+simulations for galaxy formation and evolution, challenging theoretical galaxy
+formation models to explain it. The confirmation of the Freeman Law led to a
+press release that was picked up by more than 20 news agencies world-wide in 10
+different languages. This paper is a sequel to a first paper calculating the
+scale length of the same 30000 galaxies, a result of the first EuroVO-AIDA
+Research Initiative [Fathi et al., MNRAS, 406, 1595, (2010)].

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### Argentina joins the IVOA
+
+In February 2011, The IVOA Executive Committee approved Argentina's application
+to join the IVOA. With the addition of the
+[Nuevo Observatory Virtual Argentino (NOVA)](http://nova.org.ar/), the total
+number of IVOA member organizations worldwide has now reached 19, covering four
+continents and many time zones. Argentina's membership, which follows that of
+Brazil in September 2009, demonstrates the growing interest in VO in South
+America. Informal expressions of interest have also been received recently by
+other countries in South America, Europe, and Africa. More information on IVOA
+Members and Membership can be found on the [IVOA Members](/members/) page and
+the document describing
+[Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html).

+
+### VODance
+
+VODance is a tool for rapid deployment of Virtual Observatory compliant services. This tool helps users to publish their datasets to the Virtual Observatory without dealing with the technical details, and without having to move their data. Publishing is as easy as configuring a database connection to INAF IA2 (Italian Astronomical Archive Center) pointing to the data, and providing a standardized metadata description. Virtual Observatory services are then created, providing access to the data. VODance has been successfully used to publish image and tabular data from MySQL and Oracle database management systems.

+
+### TOPCAT talks TAP
+
+TOPCAT is a powerful and easy-to-use GUI table analysis tool offering plotting,
+matching, selection, and many other facilities for exploration of large or small
+catalogues. It has extensive capabilities for accessing remote data -- from
+direct access to special purpose services such as VizieR and the Millennium
+Simulation to positional searches and positional crossmatching with remote
+catalogue, image and spectral data sets -- all powered by the VO-enabled
+services which many astronomical archives offer. The latest version, 3.8, adds
+support for the recently standardized Table Access Protocol (TAP) which allows
+SQL-like queries from a uniform interface to remote surveys and other databases,
+opening the door to much more flexible data mining than position-based
+selections, bringing the power of SQL-based queries to many more data sets.

+
+### EURO-VO scientific tutorials
+
+In the past three years, as a result of the three VO Schools organised by the
+EURO-VO, a number of science tutorials using VO tools and services have been
+made available online. These science cases include examples from both galactic
+and extragalactic astronomy and explore VO capabilities such as accessing
+images, spectra and catalogues of individual objects or lists of objects
+simultaneously, cross-correlating large catalogues, combining images coming from
+different observatories/instruments/wavelengths, analysing spectral lines, and
+more. The tutorials are being kept up-to-date to reflect the latest versions of
+the various tools.

+### Featured Paper
+
+[A search for new hot subdwarf stars by means of Virtual Observatory tools](http://adsabs.harvard.edu/abs/2011A%26A...530A...2O)
+
+Oreiro et al., 2011, A&A, 530, A2
+
+Hot subdwarf stars are faint, blue objects whose origin is still uncertain.
+Increasing the number of detections is crucial to undertake statistical studies
+that could shed light on this question. This work describes a strategy to find
+new, uncatalogued hot subdwarfs making use of Virtual Observatory tools. More
+precisely, VO applications were used to collect photometry from very large
+surveys, namely GALEX and 2MASS, in order to select adequate subdwarf
+candidates, to build and fit the spectral energy distribution of these
+candidates and estimate their effective temperature, Teff, before heading to the
+telescope for spectroscopic confirmation. The high success rate (the
+contamination factor is of only 13%) demonstrates the validity of the
+methodology and its application to the entire sky will be presented in a
+forthcoming work.

+
+[Astroinformatics of galaxies and quasars: a new general method for photometric redshifts estimation](http://adsabs.harvard.edu/abs/2011arXiv1107.3160L)
+
+Laurino, O.; D'Abrusco, R.; Longo, G.; Riccio, G.
+
+With the availability of the huge amounts of data produced by current and future
+large multi-band photometric surveys, photometric redshifts have become a
+crucial tool for extragalactic astronomy and cosmology. In this paper we present
+a novel method, called Weak Gated Experts (WGE), which allows to derive
+photometric redshifts through a combination of data mining techniques. The WGE,
+like many other machine learning techniques, is based on the exploitation of a
+spectroscopic knowledge base composed by sources for which a spectroscopic value
+of the redshift is available. This method achieves a variance in the redshift
+residuals (zphot - zspec) of 2.3x10-4 and 0.08 for the reconstruction of the
+photometric redshifts for the optical galaxies from the SDSS and for the optical
+quasars respectively, while the Root Mean Square (RMS) of the redshift residuals
+distributions for the two experiments is respectively equal to 0.021 and 0.35.
+The WGE provides also a mechanism for the estimation of the accuracy of each
+photometric redshift. We also present and discuss the catalogs obtained for the
+optical SDSS galaxies, for the optical candidate quasars extracted from the DR7
+SDSS photometric dataset, and for optical SDSS candidate quasars observed by
+GALEX in the UV range. The WGE method exploits the new technological paradigm
+provided by the Virtual Observatory and the emerging field of Astroinformatics.

+
+> This issue is dedicated to the memory of
+> [Dr. Dave De Young](http://www.usvao.org/news/?p=261), one of the pioneers of
+> the Virtual Observatory movement. Dave, who was an astronomer at NOAO from 1980
+> until his retirement in September 2011, was Project Scientist of the National
+> Virtual Observatory (2002-2009) and of the Virtual Astronomical Observatory
+> (2009-2011). He was a a great source of strength and inspiration for the IVOA,
+> of which he was the Vice-Chair (2006-2007) and Chair (2007-2008). Through his
+> role as the Chair of the Standing Committee on Science Priorities (2008-2011)
+> Dave did much to target VO efforts towards applications to scientific issues,
+> rather than just technology development. Dave's presence will be greatly missed
+> at IVOA meetings, during the sessions, as well as in the evenings where he
+> dazzled everyone with his knowledge, wisdom and personality.

+
+### VOSA (VO Sed Analyzer) 3.0
+
+VOSA is a tool developed by the Spanish VO to determine physical parameters
+(e.g. temperatures, gravities, masses, ages) of astronomical objects through the
+comparison of photometry gathered from VO services, with collections of
+theoretical models. VOSA 3.0 represents a profound change with respect to
+previous versions: new VO services, new theoretical collections, and new
+functionalities such as template fitting and estimation of the extinction,
+making VOSA a powerful tool in many areas of research astrophysics. VOSA can
+also be used as a platform to develop new specific applications for different
+astrophysical problems benefiting from a common methodological base (e.g.,
+[Sanchez-Janssen 2011IAUS..277..230S](http://adsabs.harvard.edu/abs/2011IAUS..277..230S)).

+
+### VOPlot v1.8 Beta
+
+VOPlot v1.8Beta includes many enhancements and bug fixes. To name a few v1.8Beta
+supports multi-grid plots for 2D Scatter-Plot which allows the user to have
+multiple plots having grid size from 1x1 to 3x3 in a single window. Paginated
+view is added to see data in tabular format which allows user to navigate
+systematically. Provision to label Lat/Long lines is also added. Users can now
+plot a cumulative histogram for all histogram types. VOPlot 1.8Beta shows the
+metadata of a FITS file instantaneously while the actual loading happens in
+background. VOPlot v1.8Beta also provides better handling of "faulty data" while
+parsing an ASCII file.

+### CDS XMatch Service
+
+CDS Xmatch is a new service for efficient positional cross-matching of very
+large catalogues. Input catalogues include all (~10000) VizieR tables, a tabular
+view of the Simbad database, plus GALEX, UKIDSS DR5 LAS, SDSS DR8, and
+user-uploaded tables. The service has been designed for large jobs; for example,
+the entire SDSS DR8 can be cross-matched with the 2MASS point source catalogue
+in less than 17 minutes, resulting in ~55x106 cross-matched associations with
+separations <2.5", and producing a ~15GB output file.

+### Featured Paper
+
+[Identification of red high proper-motion objects in Tycho-2 and 2MASS catalogues using Virtual Observatory tools](http://adsabs.harvard.edu/abs/2012arXiv1201.5315J)
+
+Jiménez-Esteban, F. M.; Caballero, J. A.; Dorda, R.; Miles-Páez, P. A.; Solano, E.
+
+Astronomy & Astrophysics, Volume 539, id.A86
+
+With available Virtual Observatory tools, we looked for new M dwarfs in the
+solar neighbourhood and M giants with high tangential velocities. From an
+all-sky cross-match between the optical Tycho-2 and the near-infrared 2MASS
+catalogues, we selected objects with proper motions μ > 50 mas yr-1 and very red
+VT - Ks colours. For the most interesting targets, we collected multi-wavelength
+photometry, constructed spectral energy distributions, estimated effective
+temperatures and surface gravities from fits to atmospheric models, performed
+time-series analysis of ASAS V-band light curves, and assigned spectral types
+from low-resolution spectroscopy obtained with CAFOS at the 2.2 m Calar Alto
+telescope. We got a sample of 59 bright red high proper-motion objects,
+including fifty red giants, four red dwarfs, and five objects reported in this
+work for the first time. The five new stars have magnitudes VT ≈ 10.8-11.3 mag,
+reduced proper motions midway between known dwarfs and giants, near-infrared
+colours typical of giants, and effective temperatures Teff ≈ 2900-3400 K. From
+our time-series analysis, we discovered a long secondary period in Ruber 4 and
+an extremely long primary period in Ruber 6. With the CAFOS spectra, we
+confirmed the red giant nature of Ruber 7 and 8, the last of which seems to be
+one of the brightest metal-poor M giants ever identified.

+### VOSpec version 6.5 - Photometry now in VOSpec!
+
+The ESA-VO team is pleased to announce the release of VOSpec version 6.5. The
+new version accesses early photometry services from the NASA/IPAC Extragalactic
+Database (NED) and CDS VizieR. Spectra from Simple Spectral Access (SSAP)
+services can now be combined with photometric data from VizieR and NED databases
+to build combined Spectral Energy Distributions (SEDs) that fulfil new science
+cases. The following videos demonstrate the new capabilities:

+### VisIVO Science Gateway
+
+The new product of the VisIVO family is a science gateway aimed at creating a
+working environment for analysis and visualization of astrophysical data. This
+product offers its services through a web portal that has been deployed in the
+SCIentific Gateway Based User Support (SCI-BUS) project, a European Commission
+funded project. This project is a web environment in which the scientist can
+design pipelines (workflow is the technological object that better implements
+the “pipeline” concept), share them, and seamlessly run them on clusters,
+service grids or desktop grids. There are several ready-to-use visualization
+workflows that allow the scientist to import data and build interactively
+customized 3D visualization and movies using VisIVO visualization tool that is
+embedded in the gateway.

+### TAPHandle: Accessing multiple TAP services from your Browser
+
+TAPHandle is a web application designed to mine multiple Table Access Protocol
+(TAP) resources from a simple browser. TAP services provide SQL-like access to
+astronomical tables and databases. TAP services accessed by TAPHandle are
+presented as one single browsable resource. This tool helps to explore tables by
+showing the columns available and enables users to formulate queries without
+typing code. A shopping cart service allows the user to download multiple
+resources of interest in one archive. The retrieved data files pass through a
+dynamic filter that binds data sets to appropriate applications (preview, SAMP
+clients) according to their content description and access format. The last
+release also enables browsing of huge TAP services such as Vizier.

+### Taverna looks at the sky
+
+AstroTaverna is a plugin for the Taverna 2.4 workflow engine that packages VO
+web services and existing astronomical tools such as Sesame and STILTS for use
+as building blocks to construct workflows. Capabilities include searching the VO
+registry for services to query remote catalogue, image and spectral archives,
+efficient manipulation and display of table data and metadata, name resolution,
+sky coordinate conversions, and more. AstroTaverna is developed within the

+### AppLauncher and SAMP Become Transparent
+
+AppLauncher is the new Jean-Marie Mariotti Center (JMMC) software to
+automatically start Simple Application Messaging Protocol (SAMP) applications
+'on-demand'. SAMP applications use the SAMP protocol to interoperate and
+communicate with one another. With AppLauncher there is now no more need to have
+applications running to send them SAMP messages, AppLauncher manages the process
+for you. Users will also easily discover tools they do not yet know, through
+SAMP or with the provided Application Dock. AppLauncher is freely available on
+the JMMC website, and the technical group is eager to receive your feedback and
+include any new software in it.

+### Featured Paper
+
+[Multiband Study of Radio Sources of the Rcr Catalogue with Virtual Observatory Tools](http://adsabs.harvard.edu/abs/2012BaltA..21..371Z)
+
+Zhelenkova, O. P.; Soboleva, N. S.; Majorova, E. K.; Temirova, A. V.
+
+Baltic Astronomy, Vol. 21, p. 371-378
+
+We present early results of our multiband study of the RATAN Cold Revised (RCR)
+catalogue obtained from seven cycles of the ``Cold'' survey carried with the
+RATAN-600 radio telescope at 7.6 cm in 1980--1999, at the declination of the SS
+433 source. We used the 2MASS and LAS UKIDSS infrared surveys, the DSS-II and
+SDSS DR7 optical surveys, as well as the USNO-B1 and GSC-II catalogues, the
+VLSS, TXS, NVSS, FIRST and GB6 radio surveys to accumulate information about the
+sources. For radio sources that have no detectable optical candidate in optical
+or infrared catalogues, we additionally looked through images in several bands
+from the SDSS, LAS UKIDSS, DPOSS, 2MASS surveys and also used co-added frames in
+different bands. We reliably identified 76% of radio sources of the RCR
+catalogue. We used the ALADIN and SAOImage DS9 scripting capabilities,
+interoperability services of ALADIN and TOPCAT, and also other Virtual
+Observatory (VO) tools and resources, such as CASJobs, NED, Vizier, and WSA, for
+effective data access, visualization and analysis. Without VO tools it would
+have been problematic to perform our study.

+**The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 19 VO programs from Argentina, Armenia, Australia,
+Brazil, Canada, China, Europe, France, Germany, Hungary, India, Italy, Japan,
+Russia, Spain, Ukraine, the United Kingdom, and the United States and an
+inter-governmental organization (ESA). Membership is open to other national and
+international programs according to the IVOA Guidelines for Participation. You
+can read more about the IVOA and what we do at .**
+
+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+# IVOA news
+
+New IVOA website! The IVOA is pleased to announce a shiny new version of our
+website (). As well as an attractive new design and general
+wash and brush-up, the idea was to improve the navigational structure. Different
+types of visitors can follow different paths. Very general information about the
+IVOA as an organization can be found in the "[About](/about/)" section.
+Scientists who want to find out what the VO is about, and how to use VO tools to
+do science, should use the "[Astronomers](/astronomers/)" section - in this
+section there is also a page about the
+[VO for students and the general public](/astronomers/vo_for_public/). Technical
+types, for example, applications writers, or data center staff who want to
+deploy services, can find much more nitty gritty detail in the
+"[Deployers](/deployers/)" section. Last but not least, people who are actually
+participating in IVOA standards development and discussion can get straight to
+their favourite working group mailing lists and so on, in the
+"[Members](/members/)" section. We hope you enjoy the new look!

+
+### VOPlot
+
+VOPlot is a tool for visualizing astronomical data, and acts on data available
+in VOTABLE, ASCII and FITS formats. VOPlot has undergone considerable
+improvements in the past couple of years and incremental versions have been
+released regularly. The latest version features Table Access Protocol (TAP),
+allowing users to query TAP compatible catalogs. The helpset is now bundled
+within VOPlot. Minor ticks have been included within the plot properties. Users
+can view the points with a greater precision, in order to pinpoint the point
+location. A new functionality makes it possible to draw a line between any two
+points in the graph. An updated user guide is released with v1.8.

+
+### Aladin lite: a simple visualizer for the browser
+
+CDS is releasing the first version of Aladin lite, a light version of Aladin
+running in the browser and geared towards simple visualization of a sky region.
+The first version allows one to visualize image surveys (JPEG multi-resolution
+HEALPix all-sky surveys) and superimpose tabular (VOTable) and footprints
+(STC-S) data. Aladin lite is powered by the HTML5 canvas technology, supported
+on many platforms including desktop browsers, tablets, adn smartphones. It is
+intended to replace the Aladin Java applet technology. The full-featured Aladin
+Java version will still be developed and will be oriented for standalone usage
+only. Aladin lite is easily embeddable on any web page (a few dozen KB) and can
+also be controlled through a Javascript API.

+
+### AstroStat
+
+VO-India has recently released AstroStat, a tool that allows astronomers to use
+both simple and sophisticated statistical routines on large datasets. This tool
+uses a large public-domain statistical computing package called R. AstroStat has
+a visual interface that is easy to comprehend and results are presented in a
+well formatted manner with focus on important output parameters. It uses a third
+party R library 'ggplot2' to create publication quality graphs. Help sections
+explaining all the routines in sufficient detail are built into AstroStat. A TAP
+client has been integrated into AstroStat to access data from TAP compatible
+catalogs. AstroStat is a significant improvement over a previous similar tool by
+VO-India for statistical analysis.

+
+### Iris - Added capabilities for SED analysis
+
+Iris, the VAO SED analysis tool, has been upgraded in v1.2 with visualization
+capabilities that include a SED segment browser, metadata filtering by boolean
+expression, and display of individual point metadata. A plug-in framework has
+been added so that users can extend Iris to perform their own specific tasks.
+The ASDC group has developed a plug-in that is packaged with Iris. This plug-in
+serves to provide data from the ASDC SED data holdings, and also provides an
+example of how users can develop their own plug-ins.

+{{< side-image image="seleste.png" position="right" >}}
+
+### seleste
+
+seleste is a tool that uses VO TAP standards and ADQL protocols to access
+archives that expose tabular data, and query them using a uniform interface.
+Compared to applications designed to query specific datasets at a specific
+location using pre-defined query forms, seleste allows ad-hoc queries against
+any discoverable archive through a common interface. The architecture includes
+an application with a graphical user interface, a set of command line tools, and
+a library that interoperates with VO services and applications. Catalogs already
+available include: the Chandra Source Catalog, SDSS, 2MASS, Hipparcos, and more.
+The results of seleste queries can be saved or passed on to another VO tool,
+such as Topcat.

+
+### VO Invades Python!
+
+The Virtual Astronomical Observatory (VAO) has been busy working to bring the
+power of the VO into Python, and two products are on their way. The first,
+VAOpy, is a python package that makes it possible to query archives for images,
+catalog sources, spectra, and spectral line data, all from a python script or
+interactive session. One can also discover archives and their services by
+querying the VO registry. This package is built on top of the widely used
+AstroPy python package. The VAO has just released a beta version and is actively
+seeking feedback on its API from python developers in the community.

+### FOREST: a new heliophysics data system
+
+FOREST is a project developing a quick-look semantic search virtual observatory
+for heliophysics, which allows integration, visualisation and searching of
+observations from multiple instruments and multiple spacecraft. It aims to
+support future missions such as Solar Orbiter. FOREST uses an RDF model to
+relate observations to metadata. The data model is based on IVOA recommendations
+such as the STC, Characterisation and Observation data models. A prototype of
+FOREST with an advanced web UI frontend and a GAVO Data Center Helper Suite
+backend is under development for ESA by Skytek Ltd. and Trinity College Dublin.

+[Machine-assisted discovery of relationships in astronomy](http://adsabs.harvard.edu/doi/10.1093/mnras/stt329)
+
+_Graham, Matthew J.; Djorgovski, S. G.; Mahabal, Ashish A.; Donalek, Ciro; Drake, Andrew J._
+_Monthly Notices of the Royal Astronomical Society 2013 accepted_
+
+High-volume feature-rich data sets are becoming the bread-and-butter of 21st
+century astronomy but present significant challenges to scientific discovery. In
+particular, identifying scientifically significant relationships between sets of
+parameters is non-trivial. Similar problems in biological and geosciences have
+led to the development of systems which can explore large parameter spaces and
+identify potentially interesting sets of associations. In this paper, we
+describe the application of automated discovery systems of relationships to
+astronomical data sets, focusing on an evolutionary programming technique and an
+information-theory technique. We demonstrate their use with classical
+astronomical relationships - the Hertzsprung-Russell diagram and the Fundamental
+Plane of elliptical galaxies. We also show how they work with the issue of
+binary classification which is relevant to the next generation of large synoptic
+sky surveys, such as the Large Synoptic Survey Telescope (LSST). We find that
+comparable results to more familiar techniques, such as decision trees, are
+achievable. Finally, we consider the reality of the relationships discovered and
+how this can be used for feature selection and extraction.

+**The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia,
+Brazil, Canada, China, Europe, France, Germany, Hungary, India, Italy, Japan,
+Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United States
+and an inter-governmental organization (ESA). Membership is open to other
+national and international programs according to the
+[IVOA Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html).

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### South Africa's Astronomical Agreement for Big Data
+
+The South African National Research Foundation’s three astronomical facilities
+have formed the [South African Astroinformatics Alliance](http://www.sa3.ac.za/)
+(SA3 pronounced “SA cubed”), which serves as a virtual observatory for the
+country. South Africa hosts new and upcoming observational facilities that will
+generate huge amounts of data including the Southern African Large Telescope
+(SALT), the Karoo Array Telescope (MeerKAT) and a large part of the SKA. See
+[the SA3 announcement](http://www.saao.ac.za/sa-astroinformatics-alliance-launched/)
+of their "Astronomical agreement signed for big data!". SA3 is a member of the
+IVOA since October 2012.

+### News from VObs.it: Remote Telescope networks for schools: toward publishing educational data in VO
+
+The [European Hands-On-Universe Milky Way](http://euhou.obspm.fr/public/)
+(EUHOUMW) is an educational project funded by the European Commission to bring
+real radio observations into classrooms, where participating students use five
+remotely controlled educational radio telescopes. EUHOUMW is now evaluating how
+to publish the collected radio data in VO format to enable data sharing (e.g.
+with the Italian optical robotic telescope network), to simplify data management
+of multi-classroom projects, and to more easily incorporate professional data in
+education projects. An unofficial kick-off of the collaboration between EUHOUMW
+and VO was held in Paris, September 5-6, 2013. The topics being addressed
+included; how to tag education data alongside professional data in the VO, and
+the use of "educationalized" VO tools (following
+[educational use of Aladin and Stellarium](http://wwwas.oats.inaf.it/aidawp5/eng_download.html?fsize=medium)).
+Publishing, archiving, and maintaining educational data are topics for the
+September 2013 IVOA Interoperability and ADASS meetings.

+
+### ALMA VO Service
+
+The Japanese Virtual Observatory (JVO) and ALMA-J teams have opened a VO-based
+data distribution system for ALMA data cubes. The aim is to help users access
+public ALMA data without huge data transfers. Two user applications, ALMAWebQL
+and Vissage, were developed for this system. ALMAWebQL is a component of the JVO
+Portal and enables the user to visualize and make cut-outs of ALMA data cubes in
+a web browser, while Vissage is a desktop application to visualize downloaded
+ALMA data cubes in more detail.

+### TheoSSA
+
+The TheoSSA (Theoretical Stellar Spectra Access) service provides access to
+synthetic spectral energy distributions (SEDs) that may be calculated by any
+model-atmosphere code. The database contains pre-calculated SEDs over a wide
+range of effective temperature, surface gravity, and elemental composition. The
+related [TMAW tool](http://astro.uni-tuebingen.de/~TMAW) allows the calculation
+of individual SEDs that presently can consider opacities of the elements H, He,
+C, N, O, Ne, Na, and Mg.

+
+The TIRO (Tuebingen IRon Opacity) service constructs model atoms of Ca, Sc, Ti,
+V, Cr, Mn, Fe, Co, and Ni based on
+[Kurucz' atomic data](http://kurucz.harvard.edu/atoms.html) using a statistical
+approach (introducing super-levels and super-lines) and calculates the
+respective bound-bound and bound-free absorption cross-section.

+
+### Iris version 2.0
+
+The US VAO has released Iris 2.0, the latest version of the spectral energy
+distribution (SED) analysis tool. Iris comes with powerful new science
+capabilities which allow the redshifting, interpolation and smoothing of SEDs,
+and measurement of integrated fluxes through simple spectral bandpasses or
+through one of the thousands of photometric filters provided by the Spanish VO
+Filter Profile Service. Users can also apply simple aperture corrections to
+individual photometric points or to whole SED segments. In addition to improved
+visualization capabilities, including the co-plotting of SEDs, Iris 2.0 has
+increased interoperability with other VO tools. You can watch Iris in action in
+this [video tutorial](http://www.youtube.com/watch?v=GMaLgJfxJHI).

+### Featured Paper
+
+
+[The virtual observatory service TheoSSA: Establishing a database of synthetic stellar flux standards. I. NLTE spectral analysis of the DA-type white dwarf G 191-B2B](http://adsabs.harvard.edu/abs/2013arXiv1308.6450R)
+
+_Rauch, T.; Bohlin, R.; Kruk, J. W.; Werner, K. Astronomy & Astrophysics, in press_
+
+H-rich, DA-type white dwarfs are particularly suited as primary standard stars
+for flux calibration. State-of-the-art NLTE models consider opacities of species
+up to trans-iron elements and provide reliable synthetic stellar-atmosphere
+spectra to compare with observation. We establish a database of theoretical
+spectra of stellar flux standards that are easily accessible via a web
+interface. In the framework of the Virtual Observatory, the German Astrophysical
+Virtual Observatory developed the registered service TheoSSA. It provides easy
+access to stellar spectral energy distributions (SEDs) and is intended to ingest
+SEDs calculated by any model-atmosphere code. In case of the DA white dwarf G
+191-B2B, we demonstrate that the model reproduces not only its overall continuum
+shape but also the numerous metal lines exhibited in its ultraviolet spectrum.
+TheoSSA is in operation and contains presently a variety of SEDs for DA white
+dwarfs. It will be extended in the near future and can host SEDs of all primary
+and secondary flux standards. The spectral analysis of G 191-B2B has shown that
+our hydrostatic models reproduce the observations best at an effective
+temperature of 60000 +/- 2000K and a surface gravity of log g = 7.60 +/- 0.05.
+We newly identified Fe VI, Ni VI, and Zn IV lines. For the first time, we
+determined the photospheric zinc abundance with a logarithmic mass fraction of
+-4.89 (7.5 times solar). The abundances of He (upper limit), C, N, O, Al, Si, O,
+P, S, Fe, Ni, Ge, and Sn were precisely determined. Upper abundance limits of
+10% solar were derived for Ti, Cr, Mn, and Co. The TheoSSA database of
+theoretical SEDs of stellar flux standards guarantees that the flux calibration
+of all astronomical data and cross-calibration between different instruments can
+be based on the same models and SEDs calculated with different model-atmosphere
+codes and are easy to compare.

+**IVOA Newsletter Editors:** Mark G. Allen, Deborah Baines, Sarah Emery Bunn,
+Chenzou Cui, August Muench, Mark Taylor & Ivan Zolotukhin.
+
+** The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia,
+Brazil, Canada, Chile, China, Europe, France, Germany, Hungary, India, Italy,
+Japan, Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United
+States and an inter-governmental organization (ESA). Membership is open to other
+national and international programs according to the
+[IVOA Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html).
+You can read more about the IVOA and what we do at .**
+
+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+### Chilean Virtual Observatory (ChiVO) joins the IVOA
+
+The Chilean VO, which is supported by five Chilean universities, ALMA, and the
+REUNA research consortium, was welcomed into the IVOA at the September 2013 IVOA
+meeting. ChiVO will focus on building the tools and technology infrastructure
+necessary for Chilean researchers to take advantage of the terabytes of data
+that will be produced by ALMA. More information can be found at
+.

+
+### Moving forward with Data Standards
+
+The past six months have seen the recommendation of three new data standards. These include a [Photometry Data Model](http://ivoa.net/documents/PHOTDM/index.html) for describing photometric systems, and two specifications for data access services ([Data Access Layer Interface](http://ivoa.net/documents/DALI/index.html), [Describing Simple Data Access Services](http://ivoa.net/documents/SimpleDALRegExt/index.html)). The VOTable standard, which is an XML standard for the interchange of tables of data and metadata, moved to [version 1.3](http://www.ivoa.net/documents/VOTable/).

+
+### Theoretical Astrophysical Observatory (TAO)
+
+The Australian VO is happy to announce the launch of the TAO, which houses
+queryable data from multiple popular cosmological simulations and galaxy
+formation models. Results can be funnelled through higher-level modules to build
+custom mock galaxy catalogues and images. TAO is accessible from anywhere you
+can access the internet. TAO is part of the All-Sky Virtual Observatory (ASVO)
+and is funded and supported by Astronomy Australia Limited, the National
+eResearch Collaboration Tools and Resources (NeCTAR), and Swinburne University
+of Technology.

+
+### VO Client Release - Access the VO from your desktop
+
+The US Virtual Astronomical Observatory (VAO) has released VOClient - a software
+package that enables direct access to services in the VO from a Unix terminal or
+scripting environment. The VOClient command-line tools allow you to discover
+archives and catalogs through queries to the VAO Registry, search-for and
+download images, spectra, and catalogs, and interoperate with other
+VO-compatible tools. These tools can be used to create customized access to VO
+services, new VO tools or enhancements to existing software by adding VO
+capabilities.

+
+### Comet, a Python implementation of the VOEvent Transport Protocol
+
+VOEvent is the IVOA system for describing transient celestial events. Details of
+transients detected by many projects, including Fermi, Swift, and the Catalina
+Sky Survey, are currently made available as VOEvents, and it has been selected
+as the standard alert format by future facilities such as LSST and SKA. Comet is
+an implementation of the VOEvent Transport Protocol, which makes the fast and
+reliable distribution of VOEvents to the community possible. Comet enables you
+to subscribe to real-time streams of ongoing events, to use filters to select
+only events relevant to your science case and to publish your own events to the
+global VOEvent backbone. Comet is written in Python, is open source and is
+freely available from .

+
+### TOPCAT Visualisation
+
+TOPCAT has recently had an overhaul of its visualisation capabilities. New
+features include sky axes, the ability to plot vectors, ellipses, contours and
+analytic functions, hybrid scatter/density plots, improved 3d navigation, better
+interactive response, LaTeX labelling of axes, more configurability, and better
+performance for large (multi-million-row) tables. As well as visualisation,
+TOPCAT continues to provide a wide range of other analysis capabilities for
+tabular data including VO access, crossmatching and row selections.

+
+### CASSIS: Version 3.6.1 released
+
+The latest release of CASSIS (Centre d'Analyse Scientifique de Spectres
+Instrumentaux et Synthétiques), version 3.6.1, is available for download since
+March 4, 2014. CASSIS provides tools to visualize and analyze spectra, in
+particular to perform line identification. A number of changes have been and are
+being implemented to make CASSIS VO-compatible. CASSIS now includes a Simple
+Spectral Access (SSA) module and also allows the user to interrogate the VAMDC
+online database (http://www.vamdc.eu/access-data/portal), rather than a local
+database. Both of these features are illustrated in the accompanying figure: the
+top panel shows a SSA query on Orion with the responses from different services
+being displayed in different tabs, while the bottom panel shows the display of
+the selected ISO-LWS spectrum, overlaid with all CO transitions found in the
+VAMDC/CDMS database and potentially present in the spectrum (green lines);
+clicking on any of these lines displays the associated spectroscopic parameters.

+
+### ETC-42
+
+ETC-42 is a Generic Exposure Time Calculator developed by CeSAM/LAM. Unlike
+usual existing ETCs, it can calculate the Signal to Noise Ratio (SNR) for any
+site and instrumentation type and perform simulations for a wide range of
+existing or future telescopes. It can simulate objects using theoretical
+spectral distributions (black bodies, flat energy flux, etc) or with user
+defined (or imported via SAMP) spectra. Simulation results can be saved,
+exported or broadcast in VOTable format. A plugin framework is also available
+for pre and post process of simulations. ETC-42 provides a user friendly
+Graphical User Interface (GUI) as well as a command line mode supporting script
+execution.

+### Featured Paper
+
+[A Cross-correlation Analysis of Active Galactic Nuclei and Galaxies Using Virtual Observatory: Dependence on Virial Mass of Supermassive Black Hole](http://adsabs.harvard.edu/abs/2013ApJ...775...43K)
+**Komiya, Yutaka; Shirasaki, Yuji; Ohishi, Masatoshi; Mizumoto, Yoshihiko**
+_The Astrophysical Journal, Volume 775, Issue 1, article id. 43, 12 pp. (2_013)._
+
+We present results of the cross-correlation analysis between active galactic
+nuclei (AGNs) and galaxies at redshift 0.1-1. We obtain data of ~10, 000 Sloan
+Digital Sky Survey AGNs in which their virial masses with a supermassive black
+hole (SMBH) were estimated. The UKIDSS galaxy samples around the AGNs were
+obtained using the virtual observatory. The scale length of AGN-galaxy
+cross-correlation for all of the samples is measured to be r_0=
+5.8^{+0.8}_{-0.6}\,h^{-1}\,Mpc (for the fixed slope parameter γ = 1.8). We also
+derived a dependence of r0 on the BH mass, MBH, and found an indication of an
+increasing trend of r0 at MBH > 108 M⊙. It is suggested that the growth of SMBHs
+is mainly driven by interactions with the surrounding environment for MBH > 108
+M⊙. On the other hand, at MBH <~ 108 M⊙, we did not find the BH mass dependence.
+This would imply that for less massive BHs, the mass growth process can be
+different from that for massive BHs.

+**IVOA Newsletter Editors:** Mark G. Allen, Deborah Baines, Sarah Emery Bunn, Chenzou Cui, August Muench, Mark Taylor & Ivan Zolotukhin.
+
+**The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia,
+Brazil, Canada, Chile, China, Europe, France, Germany, Hungary, India, Italy,
+Japan, Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United
+States and an inter-governmental organization (ESA). Membership is open to other
+national and international programs according to the
+[IVOA Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html).

+
+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### Beyond the US VAO project
+
+Funding for the [US Virtual Astronomical Observatory](http://www.usvao.org/)
+project discontinued at the end of September 2014. The legacy of the VAO will be
+preserved by a combination of efforts. Starting on October 1, the NASA archives
+began sustaining key components of the US VO infrastructure developed by the
+VAO, including the website, the registry, and service monitors. The NASA
+archives will also take an active role in the IVOA going forward.
+
+All software, documentation, and other digital assets developed under the VAO is
+stored in the
+[VAO Project Repository](https://sites.google.com/site/usvirtualobservatory).
+Many VAO-developed tools and services will be sustained by the organizations
+that developed them within the VAO collaboration. For a complete list of these
+tools and services, and more information about the VAO closeout and
+continuation, please see the US VAO website
+[summary](http://www.usvao.org/2014/09/22/beyond-the-vao/).

+
+### Three more VO schools in Spain
+
+The Spanish Virtual Observatory has organized in the last months two VO schools
+in research institutes (Cantabria, June 2014; Valencia; July 2014) and one
+school in the framework of the Scientific Meeting of the Spanish Astronomical
+Society (Teruel, September 2014) with an attendance of more than 75 people. The
+main goal of the schools was to expose participants to the variety of VO tools
+and services available today so that they can use them efficiently for their own
+research. To achieve this goal, VO experts lecture and tutor the participants on
+the usage of such tools. Real life examples of scientific applications are
+given, some of them selected from the science cases proposed by the
+participants. More information on these meetings can be found on the
+[SVO website](http://svo.cab.inta-csic.es/docs/index.php?pagename=Meetings).

+
+{{< side-image image="dcworkshop.png" position="left" >}}
+
+### First SVO workshop on data publishing
+
+The Spanish Virtual Observatory organised in March 2014 a workshop on how to
+publish data in the VO. The workshop had a twofold objective: on one hand, to
+train participants on the usage of the publishing tools developed by the SVO
+through "hands-on" sessions in which they learn how to develop a VO service from
+scratch. On the other hand, to serve as a community-building exercise in which
+SVO staff and data providers know each other, data centres describe their needs
+and VO staff explains what the Virtual Observatory can offer to cover those
+needs. The workshop program and corresponding presentations have been made
+available at the
+[SVO website](http://svo.cab.inta-csic.es/svoMeetings/index.php?mid=34&action=page&pagename=Meetings/SVO_thematic_network/First_Workshop_Datapublication_SVO/Presentation).

+{{< side-image image="ProcessDiagram_crop2.png" position="right" >}}
+
+### Moving forward with Data Standards
+
+The past six months have seen the recommendation of three new data standards.
+These include a recommended syntax for writing the string representation of unit
+labels (["VOUnits"](http://ivoa.net/documents/VOUnits/)), and the introduction
+of the [Parameter Description Language (PDL)](http://ivoa.net/documents/PDL/),
+which intends to be an expressive language for self-descriptive web services
+exposing the semantic nature of input and output parameters. With the goal of
+providing fast spatial comparisons between image coverage maps, the
+[Multi-Order Coverage](http://ivoa.net/documents/MOC/) map specification reached
+version 1.0. This version is based on the [HEALPix](http://healpix.jpl.nasa.gov/)
+sky tessellation algorithm, which is one way to provide a hierarchically based
+spatial index.

+
+### Argentina Virtual Observatory's Data Center
+
+The Argentina Virtual Observatory, [NOVA](http://nova.conicet.gov.ar/),
+announces the release of its new database, powered by the
+[GAVO DACHs](http://soft.g-vo.org/dachs) technology. Data can be queried through
+specific forms at the NOVA web pages or through any VO tool such as Aladin,
+SPLAT, TOPCAT, etc. The database will be fed with material collected by
+Argentinian astronomers, and it is expected to grow rapidly in the following
+months. Currently, the NOVA database includes a JHKs merged catalogue from the
+first data release of the ESO public survey of the Milky Way bulge and southern
+plane named ''VISTA variables in the Vía Láctea'' (VVV; Saito et al 2012)..

+
+### Stat-Lite - an Android Application
+
+VO-India has recently launched Stat-Lite - an Android application that provides
+an interactive and easy introduction to the concepts of Descriptive Statistics
+and Curve Plotting. It includes basic features like loading VOTable and ASCII
+formatted datasets and performing some basic statistical analysis such as
+correlation tests, summary statistics, etc. Some of the novel features of this
+application include graphs with multi-touch gesture support allowing the user to
+pan and zoom to study specific areas, and the ability to study the effect of
+outliers on regression fits by adding them using a simple interface. The
+interface and content has been designed for high-school and undergraduate
+students. It uses 'Apache Commons Math' library for statistical calculations and
+a third party charting API called 'AChartEngine' for rendering graphs. The curve
+plotting module, apart from having all the major categories of pre-defined
+functions, has the ability to plot any arbitrary mathematical function by
+writing it down as a combination of the functions in the existing library. The
+prime motivation of this development was making useful software available on
+low-cost Aakash (Sky) Android tablets being made available to students in India.

+
+### Upgrades to the US VAO registry at STScI
+
+The VAO project has upgraded their service registry hosted at STScI, including
+major underlying database changes to support evolving IVOA standard search
+interfaces and familiar client tools including TOPCAT. Curation efforts are
+ongoing, and the database migration includes the removal of many inactive
+services across the IVOA from the registry holdings, leading to better search
+results. A formal release with documentation and available code will be part of
+the VAO closeout, as will a functional 'wizard'-like form-based interface for
+data service curators to maintain their own registered information. A RegTAP
+service based on this upgrade is in progress.

+
+### TOPCAT and CDS X-Match
+
+TOPCAT now provides integrated access to CDS's excellent
+[X-Match](http://cdsxmatch.u-strasbg.fr/) service. This means you can easily
+take a table loaded in TOPCAT and crossmatch it on sky position against any of
+the tables in the VizieR or Simbad databases, covering almost all published
+astronomical catalogues. It does the same job as TOPCAT's old multi-cone
+function, but is _much, much_ faster, typically around a million rows a minute.
+A similar function is also available from the command line using STILTS. These
+matches impose no limit on table size.

+
+### US VAO Data Discovery Tool: Version 1.7 released
+
+The US VAO released a new version of the Data Discovery Tool (v1.7) on August
+25, 2014. With this tool you can find datasets from thousands of astronomical
+collections known to the VO and over wide areas of the sky, including thousands
+of astronomical collections — photometric catalogs and images — and archives
+around the world. New features of the Data Discovery Tool include: direct search
+of the [Mikulski Archive for Space Telescopes (MAST)](http://archive.stsci.edu/),
+crossmatch search results with the major CDS catalogs via their
+[X-Match](http://cdsxmatch.u-strasbg.fr/) service, or with MAST archive
+observations, and upload a target list into the tool for the purpose of
+crossmatching.

+
+[Orion revisited. II. The foreground population to Orion A](http://adsabs.harvard.edu/abs/2014A%26A...564A..29B)
+**Bouy, H.; Alves, J.; Bertin, E.; Sarro, L. M.; Barrado, D**
+_Astronomy & Astrophysics, Volume 564, id.A29, 12 pp. (2014)._
+
+Aims: Following the recent discovery of a large population of young stars in
+front of the Orion nebula, we carried out an observational campaign with the
+DECam wide-field camera covering ≈10 deg2 centered on NGC 1980 to confirm, probe
+the extent of, and characterize this foreground population of pre-main-sequence
+stars. Methods: We used multiwavelength wide-field images and catalogs to
+identify potential foreground pre-main-sequence stars using a novel
+probabilistic technique based on a careful selection of colors and luminosities.
+Results: We confirm the presence of a large foreground population towards the
+Orion A cloud. This population contains several distinct subgroups, including
+NGC 1980 and NGC 1981, and stretches across several degrees in front of the
+Orion A cloud. By comparing the location of their sequence in various
+color-magnitude diagrams with other clusters, we found a distance and an age of
+380 pc and 5 ~ 10 Myr, in good agreement with previous estimates. Our final
+sample includes 2123 candidate members and is complete from below the
+hydrogen-burning limit to about 0.3 M⊙, where the data start to be limited by
+saturation. Extrapolating the mass function to the high masses, we estimate a
+total number of ≈2600 members in the surveyed region. Conclusions: We confirm
+the presence of a rich, contiguous, and essentially coeval population of about
+2600 foreground stars in front of the Orion A cloud, loosely clustered around
+NGC 1980, NGC 1981, and a new group in the foreground of the OMC-2/3. For the
+area of the cloud surveyed, this result implies that there are more young stars
+in the foreground population than young stars inside the cloud. Assuming a
+normal initial mass function, we estimate that between one to a few supernovae
+must have exploded in the foreground population in the past few million years,
+close to the surface of Orion A, which might be responsible, together with
+stellar winds, for the structure and star formation activity in these clouds.
+This long-overlooked foreground stellar population is of great significance,
+calling for a revision of the star formation history in this region of the
+Galaxy.

+
+### Using Virtual Observatory with Python: querying remote astronomical databases
+
+This tutorial is devoted to extending an existing catalogue with data taken
+elsewhere, either from CDS Vizier or Simbad database. As an example, we used the
+so-called 'Spectroscopic Survey of Stars in the Solar Neighborhood' (aka. S4N,
+Allende Prieto et al. 2004) in order to retrieve all objects with available data
+for the set of fundamental stellar parameters effective temperature, surface
+gravity and metallicity. Then for each object in this dataset we query Simbad
+database to retrieve the projected rotational velocity. This combines Vizier and
+Simbad queries made using Python astroquery module. The tutorial covers remote
+database access, filtering tables with arbitrary criteria, creating and writing
+your own tables, and basics of plotting in Python.

+**IVOA Newsletter Editors:** Mark G. Allen, Deborah Baines, Sarah Emery Bunn,
+Chenzou Cui, August Muench, Mark Taylor & Ivan Zolotukhin.
+
+**The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia,
+Brazil, Canada, Chile, China, Europe, France, Germany, Hungary, India, Italy,
+Japan, Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United
+States and an inter-governmental organization (ESA). Membership is open to other
+national and international programs according to the
+[IVOA Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html).
+You can read more about the IVOA and what we do at .**
+
+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### ChiVO officially launched
+
+On April 24th the Chilean Virtual Observatory (ChiVO) was officially launched to
+the community in a seminar held at Technical University Federico Santa María,
+Valparaíso, Chile.
+
+The highlights of the seminar were:
+
+* **First dataset:** ChiVO offers all the ALMA Cycle 0 FITS
+ (), which are accessible through the IVOA
+ registry under SCS, SIA, and TAP protocols.
+* **Web portal:** with information about ChiVO and a web-based interface to SCS,
+ SIA, and SSA protocols ();
+* **Ongoing projects:** presentation of the prototype tools for intelligent data
+ analysis, automatic source identification, and smart indexing, strongly
+ focused on ALMA-like spectroscopic data cubes.
+* **Community feedback:** a meeting was held with local astronomers interested
+ on publishing their datasets through ChiVO, in order to explain and
+ collaborate on this process.
+
+Please note that though ChiVO is up and running, the core services will soon be
+migrated to a dedicated data center for astronomy, which will allow ChiVO to
+properly growth as needed.

+### LAMOST DR1 Public Release
+
+LAMOST DR1 was released to the public in March, 2015, consisting of 2.2 million
+of spectra of stars, galaxies, quasars, and other unknown types. It is the
+largest astronomical spectra archive in the world. The data access system is
+developed by Chinese Virtual Observatory (China-VO) under a collaboration with
+LAMOST team. VO tools, such as Aladin and SpecView, and dedicated tools for
+LAMOST are integrated into the web portal. Search results and spectra can be
+displayed and analyzed on the fly. Large results and datasets can be retrieved
+in several ways, including FTP, wget, China-VO AstroCloud storage, and VO data
+access interfaces. Based on CDS X-Match Service, cross identification with
+dozens of well-known catalogs is provided. List of identifiers or coordinates
+supported by CDS SIMBAD and VizieR, or list of LAMOST identifiers is acceptable
+to upload and search the database in batch mode. An SDSS CasJobs mirror system
+is built with both SDSS DR12 and LAMOST DR1 catalogs inside.

+
+### CASSIS Spectral Tool updates
+
+A new version of CASSIS (free spectral tools) has been released. It is made
+availabe as either a stand alone application
+(), or it can be used via Java web
+start technology ().
+
+The CASSIS team is also announcing a change to the architecture of the software,
+and is requesting community feedback on improvements, new functionalities,
+and/or scientific uses cases to be implemented in CASSIS.
+
+To provide feedback send email to:
+[cassis-team@irap.omp.eu](mailto:cassis-team@irap.omp.eu) or for specific
+developers' questions, email:
+[cassis-dev@irap.omp.eu](mailto:cassis-dev@irap.omp.eu). Finally, a subscription
+mailing list has been created to keep users informed about recent developments
+and for users to exchange their experiences. To subscribe to this list

+
+### Advanced web application for X-ray research
+
+Following the recent release of the largest catalog of X-ray sources ever
+created, built from the XMM-Newton data and nicknamed 3XMM-DR5, the supporting
+website has been opened. For the first time it provides an intuitive search
+interface for the database of almost 400,000 X-ray sources and several advanced
+features for scientific analysis such as XSPEC-style spectral fitting of a vast
+collection of X-ray spectra right in a web browser. Built-in communication layer
+allows creation of flexible workflows to conveniently bring images, lightcurves
+and spectra of sets of X-ray objects together for detailed analysis with no
+pre-installed software required. The database also has handy connections to
+other X-ray archives and contains pre-computed cross-matches with common X-ray
+objects catalogs to facilitate easy comparison of (yet unstudied) objects of
+user interest with known CV, LMXB, HMXB, ULX, AGN and X-ray active stars. The
+success of this website research model has been demonstrated during public
+tutorials with quick-look discoveries made online.

+### New Release and upgrades to VOSA
+
+The [Spanish VO](http://svo.cab.inta-csic.es/main/index.php) will release a new
+version of VOSA in June 2015. VOSA (VO Sed Analyzer) is a web-based tool
+designed to build observational spectral energy distributions and to estimate
+physical parameters (Teff, logg, [M/H], masses, ages, etc) from comparison with
+models.
+
+We are upgrading VOSA to give an efficient estimation of the physical parameters
+of thousands of objects at a time (an order of magnitude higher compared to the
+previous version). This upgrade has required the implementation of a new
+distributed environment capable of submitting and processing jobs in an
+asynchronous and parallelized way. An improved algorithm to detect the infrared
+extinction as well as new theoretical models and observational catalogues are
+some other capabilities available in the new release.

+includes new, powerful analysis features, like integrating under fitted model
+components, a tool for statistically combining groups of SEDs, and the ability
+to arbitrarily combine template libraries and table models with other libraries,
+models, and functions. For the full list of new features and known bugs, please
+refer to the release notes at
+.
+
+You can explore all of Iris' capabilities with the User Guide at
+.
+
+To download: Iris is now downloaded and installed through Conda. Please refer to
+the new download instructions at

+### Special Issue on The Virtual Observatory
+
+A two volume special issue on the development, deployment, and impact of the
+virtual observatory was published in the Astronomy & Computing Journal between
+November 2014 and June 2015. Bob Hanisch (NIST) was Guest Editor. Comprising 28
+articles on a wide range of services, tools, infrastructure, and management of
+the virtual observatoy efforts worldwide. Complete listings of articles can be
+found for [Volume 1](http://www.sciencedirect.com/science/journal/22131337/7-8)
+and [Volume 2](http://www.sciencedirect.com/science/journal/22131337/11/part/PB)
+on the Astronomy and Computing ScienceDirect website.
+
+### Featured Science Publication
+
+[Isolated compact elliptical galaxies: Stellar systems that ran away](http://adsabs.harvard.edu/abs/2015Sci...348..418C)
+**Chilingarian, I. and Zolotukhin, I.**
+_Science, Volume 348, Page 418, 12 pp. (2015)._
+
+Compact elliptical galaxies form a rare class of stellar system (~30 presently
+known) characterized by high stellar densities and small sizes and often
+harboring metal-rich stars. They were thought to form through tidal stripping of
+massive progenitors, until two isolated objects were discovered where massive
+galaxies performing the stripping could not be identified. By mining
+astronomical survey data, we have now found 195 compact elliptical galaxies in
+all types of environment. They all share similar dynamical and stellar
+population properties. Dynamical analysis for nonisolated galaxies demonstrates
+the feasibility of their ejection from host clusters and groups by three-body
+encounters, which is in agreement with numerical simulations. Hence, isolated
+compact elliptical and isolated quiescent dwarf galaxies are tidally stripped
+systems that ran away from their hosts.

+**IVOA Newsletter Editors:** Mark G. Allen, Deborah Baines, Chenzou Cui, August
+Muench & Ivan Zolotukhin.
+
+**The International Virtual Observatory Alliance (IVOA) was formed in June 2002
+with a mission to facilitate the international coordination and collaboration
+necessary for the development and deployment of the tools, systems and
+organizational structures necessary to enable the international utilization of
+astronomical archives as an integrated and interoperating virtual observatory.
+The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia,
+Brazil, Canada, Chile, China, Europe, France, Germany, Hungary, India, Italy,
+Japan, Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United
+States and an inter-governmental organization (ESA). Membership is open to other
+national and international programs according to the
+[IVOA Guidelines for Participation](http://ivoa.net/Documents/latest/IVOAParticipation.html).
+You can read more about the IVOA and what we do at .**
+
+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### China-VO enabled Popular Supernova Project
+
+On July 29, 2015, the [Popular Supernova Project](http://psp.china-vo.org/) was
+launched. It is the first astronomical citizen science project in China as a
+joint venture between [China-VO](http://www.china-vo.org/) and
+[Xingming Amateur Astronomical Observatory](http://www.xjltp.com/xo/index-en.htm).
+In the morning of Sep. 12, a supernova candidate was discovered by a 10-year old
+pupil. Inspired by the news, number of the registered users of China-VO platform
+raised rapidly to 105K by the end of September. Currently, two supernova
+candidates discovered by public users have been confirmed by professional
+observations.
+
+The project webpage is prepared in Chinese; an English version is planned for a
+proper time in the future.

+
+### ASTERICS Virtual Observatory School
+
+The [ASTERICS](http://asterics2020.eu/) project is organising a VO School at
+Centro de Astrobiología, Madrid, Spain. The goal of the school is twofold:
+Expose European astronomers and representatives of the
+[ESFRI](http://ec.europa.eu/research/infrastructures/index_en.cfm?pg=esfri)
+projects involved in ASTERICS to the variety of VO tools and services available
+today so that they can use them efficiently for their own research and gather
+requirement and feedback from them.
+
+Important dates:
+
+* Deadline for submission of participants' use cases:
+ 13 November 2015
+* Deadline for registration:
+ 30 November 2015
+* Meeting:
+ 15-17 December 2015
+
+More information can be found at the school

+### WWT Guided Tour Design Competition
+
+The award ceremony of the 2nd WWT Guided Tour Contest was held on July 28, 2015.
+The contest was organized by [China-VO](http://www.china-vo.org/), Microsoft
+Research and other partners, began in early 2015, and was designed to promote
+the concept of scientific data-based science education and the open sharing of
+scientific and technological resources and knowledge. About 100 tours were
+submitted by school students and amateur astronomers. Videos of awarded tours
+are released to the public at .

+
+### ESA Sky: the ESA Astronomy Multi-Mission Interface
+
+We are pleased to announce the beta v1.0 release of ESA Sky, the ESA Astronomy
+Multi-Mission Interface, a science-driven discovery portal for all ESA Astronomy
+missions. ESA Sky provides simplified access to high level science-ready data
+products from ESA Astronomy missions and a number of ESA produced source
+catalogues. No prior knowledge of the involved ESA missions is needed, simply
+explore the sky with the sky exploration interface, or conduct single or
+multiple target searches. From a technical point of view, the system offers new
+all-sky multi-resolution maps of full mission datasets; detailed geometrical
+footprints to connect the all-sky mosaics to individual observations; direct
+access to the underlying mission-specific science archives; and uses the TAP and
+MOC VO protocols. The beta release contains data (imaging only) and catalogues
+from the following missions: INTEGRAL, XMM-Newton, HST, Hipparcos, ISO,
+Herschel, and Planck.
+
+We are extremely interested in your feedback and would like to hear from you via
+our [helpdesk](https://support.cosmos.esa.int/esdc/). You can see a
+[video demo](https://youtu.be/e4VUW7WCbKk?t=7m20s) of the ESA Sky beta or try
+the [beta interface](http://archives.esac.esa.int/esasky-beta).

+
+### The Keck Observatory Archive
+
+The Keck Observatory Archive (KOA) ([website](https://koa.ipac.caltech.edu/)) has released a program-friendly interface to public images acquired with all nine Keck instruments equipped with an imaging mode. The interface is compliant with the latest VO-image access standard, Simple Image Access Protocol (SIAP_ v2, June, 2015). The interface is fully [documented](https://koa.ipac.caltech.edu/UserGuide/program_interface.html) and includes a detailed description of the input and output parameters, examples for each instrument, a troubleshooting guide and a web-based query builder that allows users to create queries that are later run from a program.

+
+### TAO v2.0: The Theoretical Astrophysical Observatory
+
+The [Theoretical Astrophysical Observatory](https://tao.asvo.org.au/) (TAO)
+houses data from popular cosmological N-body simulations and semi-analytic
+galaxy formation models, primarily focused on survey science. Mock catalogues
+can be built from the database without the need for any coding. Results can be
+funnelled through higher-level modules to build custom light-cones and images.
+TAO is accessible from anywhere you can access the internet.
+
+TAO v2.0 has just been released with many front and back-end enhancements. These
+include the option to download premade mock catalogues (e.g. created in advance
+for a specific survey, like CANDELS or SDSS), significant improvements to the
+image module to make it easier to image your mock galaxies, and an update of the
+SAGE semi-analytic model to its public release version
+([Croton et al. 2015](https://github.com/darrencroton/sage)). Head over to TAO
+now and build your own universe!

+
+### TOPCAT TAP Improvements
+
+The recent release (v4.3) of the table analysis tool TOPCAT features a major
+overhaul of its TAP window. TAP, the Table Access Protocol, lets you run
+flexible SQL-like queries on remote astronomical databases. The updated TAP
+window is easier to use and more powerful than before: improvements include the
+ability to search for datasets by table name or description, better query
+editing facilities, more useful information about the service you're using, and
+a list of example queries to help you write your own, including examples
+specific to the current database. It also now works well with very large TAP
+services, including HEASARC from NASA (900 tables) and VizieR from CDS (30,000
+tables).

+[The number fraction of discs around brown dwarfs in Orion OB1a and the 25 Orionis group](http://adsabs.harvard.edu/abs/2015MNRAS.450.3490D)
+**Downes, Juan José; Román-Zúñiga, Carlos; Ballesteros-Paredes, Javier; Mateu,
+Cecilia; Briceño, César; Hernández, Jesús; Petr-Gotzens, Monika G.; Calvet,
+Nuria; Hartmann, Lee; Mauco, Karina.**
+_Monthly Notices of the Royal Astronomical Society, Vol. 450, 3490-3502 (2015)._
+
+We present a study of 15 new brown dwarfs belonging to the ˜7 Myr old 25 Orionis
+group and Orion OB1a subassociation with spectral types between M6 and M9 and
+estimated masses between ˜0.07 and ˜0.01 M⊙. By comparing them through a
+Bayesian method with low-mass stars (0.8 ≲ M/M⊙ ≲ 0.1) from previous works in
+the 25 Orionis group, we found statistically significant differences in the
+number fraction of classical T Tauri stars, Weak T Tauri stars, class II,
+evolved discs and purely photospheric emitters at both sides of the substellar
+mass limit. Particularly, we found a fraction of 3.9^{+2.4}_{-1.6} per cent
+low-mass stars classified as Classic T Tauri star and class II or evolved discs,
+against a fraction of 33.3^{+10.8}_{-9.8} per cent in the substellar mass
+domain. Our results support the suggested scenario in which the dissipation of
+discs is less efficient for decreasing mass of the central object.

+The 14th September 2016 saw the release of the long awaited Gaia Data Release 1
+(DR1), which includes positions and G magnitudes for over 1 billion sources, the
+five-parameter astrometric solution for over 2 million sources (Tycho-Gaia
+Astrometric Solution, TGAS), photometric data of selected RR Lyrae and Cepheid
+variable stars, positions and G magnitudes for over 2000 quasars, and
+cross-matches between Gaia sources and many other catalogues (see
+[here](http://www.cosmos.esa.int/web/gaia/dr1) for the full list of contents).
+Many of the IVOA member organisations and individual members have played an
+important role in the Gaia Data Processing and Analysis Consortium
+([DPAC](http://www.cosmos.esa.int/web/gaia/dpac/consortium)), and as such, a
+host of data centres and institutes are now providing the Gaia DR1 data using VO
+protocols. These data centres and institutes include ESA's
+[ESAC Science Data Centre (ESDC)](http://archives.esac.esa.int/),
+[Centre de Données astronomiques de Strasbourg (CDS)](http://cds.unistra.fr/gaia),
+[Astronomisches Rechen-Institut (ARI)](http://gaia.ari.uni-heidelberg.de/),
+[Leibniz-Institute for Astrophysics Potsdam (AIP)](https://gaia.aip.de/) and the
+[ASI Science Data Center (ASDC)](http://gaiaportal.asdc.asi.it/). Other
+institutes around the world are also hosting the Gaia DR1 data, these include
+the [Japanese Virtual Observatory](http://jvo.nao.ac.jp/portal/gaia.do),
+[NASA/IPAC Infrared Science Archive](http://irsa.ipac.caltech.edu/cgi-bin/Gator/nph-scan?projshort=Gaia)
+and the [German Astrophysical Virtual Observatory (GAVO)](http://dc.zah.uni-heidelberg.de/__system__/dc_tables/list/form).
+Additionally, new functionalities to access and analyse Gaia data have been
+implemented in a number of VO Tools, including
+[Aladin Desktop](http://aladin.u-strasbg.fr/AladinDesktop/),
+[TOPCAT](http://www.star.bris.ac.uk/~mbt/topcat/) and
+[VOSA](http://svo2.cab.inta-csic.es/theory/vosa/). Within this newsletter, we
+highlight some of the data centres and VO tools providing access to Gaia data
+using VO protocols.

+
+### Gaia DR1 at ESA
+
+The [ESA Gaia Archive](http://archives.esac.esa.int/gaia) was released to the
+public on the 14th September 2016 with
+[Gaia DR1](http://www.cosmos.esa.int/web/gaia/dr1). As the official repository
+for Gaia data, it has been validated by the DPAC consortium and provides access
+to all of the DR1 data. Being a VO inside archive based in TAP, its services are
+fully interoperable and available from VO tools (eg. Topcat). Its back-end
+infrastructure allows users to perform SQL analytics over billion scale
+catalogues. While keeping compatibility with TAP 1.0, the protocol has been
+extended to TAP+, providing authentication, stateful uploads, server side
+crossmatches and other functionalities, allowing data analysis to move closer to
+the data.
+
+Gaia DR1 catalogues are also available via [ESASky](http://sky.esa.int/), a
+science driven discovery portal for space-based astronomy missions.
+
+The ESA Gaia Archive can be accessed at:

+
+### Gaia DR1 at CDS
+
+Gaia DR1 data are available since September 14th in CDS services: VizieR, Aladin
+and the CDS cross-matching service. In addition to the regular
+[VizieR interface](http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=I/337), VO
+access is provided through cone search queries and through TAP allowing the user
+to formulate SQL-like queries from our
+[web interface](http://tapvizier.u-strasbg.fr/adql/?I/337) or from any TAP
+client (Topcat or TAPHandle for instance). Aladin Desktop features a dedicated
+form for easy access to Gaia data and visualization of proper motions. The
+cross-match service offers fast spatial cross-identifications of Gaia data with
+VizieR 16,000+ tables with positions or user-uploaded tables. Access to the
+cross-match is done either via our
+[web page](http://cdsxmatch.u-strasbg.fr/) or via Topcat. Gaia DR1 has also been
+made available as HiPS progressive catalogues, seamlessly browsable from Aladin
+Desktop and Aladin Lite as demonstrated
+[here](http://cds.unistra.fr/Gaia/DR1/AL-visualisation.gml).

+
+### Gaia DR1 at ARI
+
+The Astronomisches Rechen Institut (ARI) in Heidelberg (Germany) is one of the
+few institutes officially publishing the Gaia data. It is providing access to
+the Gaia catalogue through three services:
+
+* **Single Source Search:** it is a simple service returning the closest Gaia
+ (or TGAS) source from a given position, object name (resolved by Simbad) or
+ Gaia source ID. It is not a VO service and is then accessible only on the web
+ page or by HTTP requests using tools like wget or curl.
+* **Cone Search:** it is following the IVOA standard SCS. There is one entry for
+ Gaia and another one for TGAS. Both are registered in the VO Registry and are
+ then easily accessible through VO clients like TOPCAT.
+* **TAP:** eight Gaia DR1 tables and some famous catalogues can be queried here
+ using the freedom of ADQL. This service is also listed in the VO Registry.
+
+A nice feature for data discovery has been added to this TAP service: metadata
+describing the numerical columns with simple summary statistics (e.g. mean,
+quartiles, min, max). These additional pieces of information are visible in
+TOPCAT (versions >= 4.3-4). Besides, histograms and sky maps for the same
+catalogue columns can also be seen and downloaded through the web site. These
+sky-maps show the average value of the represented catalogue column on the whole
+sky using Healpix maps (which can be downloaded and displayed in Aladin for more
+interactivity). Of course a density map for almost all published tables is also
+available.

+
+### Second ASTERICS Virtual Observatory School
+
+The [ASTERICS](http://asterics2020.eu/) project held its second VO school at the
+Observatoire Astronomique de Strasbourg, France, on 15-17 November 2016. The
+goal of the school was twofold: to expose European astronomers and
+representatives of the
+[ESFRI](http://ec.europa.eu/research/infrastructures/index_en.cfm?pg=esfri)
+projects involved in ASTERICS to the variety of VO tools and services available
+today so that they can use them efficiently for their own research; and to
+gather requirements and feedback from participants.
+
+During the first two days, VO experts gave hands-on sessions on the usage of VO
+tools and services using real life examples of scientific applications. A large
+fraction of the time was dedicated to hands-on exercises using real life
+examples of scientific applications, which allowed participants to become fully
+familiar with the VO capabilities on their own laptops. The last day was then
+dedicated to the participants own science cases, applying what they had learnt
+earlier in the week.
+
+More information can be found

+### Gaia Data Access Workshop in Heidelberg
+
+From 21st to 24th November 2016 the Gaia Data Access Workshop took place at the
+"Haus der Astronomie" in Heidelberg. Organised by the GAVO and Gaia groups at
+ARI/ZAH and in collaboration with CDS and AIP, the 57 participants learned about
+the contents of Gaia DR1 and about warnings and caveats using them. In hands-on
+tutorial sessions the particpants learned how to use TAP and ADQL to access the
+Gaia data via TOPCAT. The Gaia data centres at ARI, CDS, AIP and ESAC presented
+the different features of their services and how to use them for using the Gaia
+data.
+
+Overall the (secret) aim of using Gaia as an opportunity for VO outreach was a
+success.

+
+APOGEO (Automatic POrtal GEneratOr) is a tool under development at IA2 that
+automatizes the creation of web interfaces for querying astronomical archives,
+after an administrator performs a proper configuration process guided by a
+graphical wizard. It is possible to select which tables to use for queries,
+design the search form interface and customize the layout. The output of the
+generation is a package that can be deployed in an application server. The
+generated portal is able to query the astronomical archive, manage users login,
+retrieve astronomical images consistently with configured data access policies
+and send tabular data (VOTables) and files to external applications using the
+SAMP VO standard.

+
+### CASSIS New Release
+
+The CASSIS Team will release a new version (4.0) of the free spectral tool in
+November 2016. CASSIS (Centre d'Analyse Scientifique de Spectres Instrumentaux
+et Synthétiques) is a Java tool designed to visualize, treat and analyze
+observational and synthetic spectra. It uses several pieces of information to
+allow the user to perform these tasks: atomic and molecular spectroscopic
+databases, radiative transfer models and access to other synthetic and
+observational spectra through SAMP, SSA and user files.
+
+In this new version, we have upgraded the tool to use the EPN-TAP protocol to
+access spectra from the services of the solar and planetary community. To do
+that, we use an independent java library tool developed in collaboration between
+the CDPP (Centre de Données de la Physique des Plasmas) and CASSIS, as part of
+the Europlanet H2020 project.
+
+Furthermore, we have improved the access to the VAMDC service (Virtual and
+Molecular Data Center). Users can now access up to 12 services containing
+thousands of species and hundreds of millions of transitions.

+
+Gaia is a European Space Agency (ESA) satellite mission, with the aim of
+creating a three-dimensional map of our Galaxy. In the process of measuring the
+positions, distances and motions of about a billion stars in the Milky Way Gaia
+will also observe thousands of transient events. The
+[Gaia Alerts project](https://gaia.ac.uk/) is working to find these events in
+the Gaia data, and to announce them to the world in real time.
+
+The Gaia alerts team has been publishing these discoveries in
+[various formats](http://gsaweb.ast.cam.ac.uk/alerts/tools) to enable follow-up,
+including a dedicated web page for every alert. Beginning on 1st November, Gaia
+alerts will also be broadcast as VOEvents at this

+
+[Search for associations containing young stars (SACY). VII. New stellar and substellar candidate members in the young associations](http://adsabs.harvard.edu/abs/2016A%26A...590A..13E)
+**Elliott, P.; Bayo, A.; Melo, C. H. F.; Torres, C. A. O.; Sterzik, M. F.; Quast, G. R.; Montes, D.; Brahm, R.**
+_Astronomy & Astrophysics (2016) Vol. 590, A13, 28 pp._
+
+
+Context. The young associations offer us one of the best opportunities to study
+the properties of young stellar and substellar objects and to directly image
+planets thanks to their proximity (<200 pc) and age (≈5-150 Myr). However, many
+previous works have been limited to identifying the brighter, more active
+members (≈1 M⊙) owing to photometric survey sensitivities limiting the
+detections of lower mass objects.
+
+Aims: We search the field of view of 542 previously identified members of the
+young associations to identify wide or extremely wide (1000-100 000 au in
+physical separation) companions. Methods: We combined 2MASS near-infrared
+photometry (J, H, K) with proper motion values (from UCAC4, PPMXL, NOMAD) to
+identify companions in the field of view of known members. We collated further
+photometry and spectroscopy from the literature and conducted our own
+high-resolution spectroscopic observations for a subsample of candidate members.
+This complementary information allowed us to assess the efficiency of our
+method.
+
+Results: We identified 84 targets (45: 0.2-1.3 M⊙, 17: 0.08-0.2 M⊙, 22: <0.08
+M⊙) in our analysis, ten of which have been identified from spectroscopic
+analysis in previous young association works. For 33 of these 84, we were able
+to further assess their membership using a variety of properties (X-ray
+emission, UV excess, Hα, lithium and K I equivalent widths, radial velocities,
+and CaH indices). We derive a success rate of 76-88% for this technique based on
+the consistency of these properties.
+
+Conclusions: Once confirmed, the targets identified in this work would
+significantly improve our knowledge of the lower mass end of the young
+associations. Additionally, these targets would make an ideal new sample for the
+identification and study of planets around nearby young stars. Given the
+predicted substellar mass of the majority of these new candidate members and
+their proximity, high-contrast imaging techniques would facilitate the search
+for new low-mass planets.

+### IAU Working Group on Data Driven Astronomy Education and Public Outreach (DAEPO)
+
+The new approved IAU Inter-Commission B2-C1-C2 WG on Data Driven Astronomy
+Education and Public Outreach (DAEPO) was launched officially in April 2017. The
+WG consists of 16 founding members, including the IVOA Education Interest Group,

+
+With the development of many mega-science astronomical projects, for example
+CTA, DESI, EUCLID, FAST, GAIA, JWST, LAMOST, LSST, SDSS, SKA, and large scale
+simulations, astronomy has become a Big Data science. Astronomical data are not
+only a necessary resource for scientific research, but also a very valuable
+resource for education and public outreach (EPO), especially in the era of the

+### Shanghai IVOA Interoperability Meeting
+
+The Northern Spring meeting of the IVOA was held on May 14-19 2017, in Shanghai,
+China, under the auspices of the China-VO. This meeting also celebrated the 15th
+anniversary of the IVOA, was among the best attended by the IVOA community (116
+registered participants) and led to productive discussions at all levels of
+participation.
+
+Since the last Interoperability meeting (in Trieste, Italy, October 2016,) a
+record 10 new standards were finalized by the Working Groups, discussed and
+approved within the Technical Coordination Group of Working and Interest Group
+Chairs, and approved by the IVOA Executive Committee. The IVOA has reached an
+important milestone for simple cube data extraction, and is now preparing the
+standards for a more complete and sophisticated manipulation of data cubes. Also
+of note is the approval of the HiPS 1.0 standard, to allow large area
+hierarchical mapping and display of astronomical data.
+
+The IVOA has now two new groups: the Media Group and the Solar System Interest
+Group. The Media Group is taking over the public face of the IVOA, including the
+publishing of newsletters and looking at different media presences. The Solar
+System Interest group will work with all IVOA working groups to review, assess
+and propose IVOA standard adjustments for Solar System sciences.
+
+The IVOA Committee on Science Priorities (CSP) tried a new approach at this
+meeting: in addition to key invited presentations on major science topics and
+projects, we had a series of short talks highlighting recent science/VO
+developments. This format will also be used in future meetings, to facilitate
+active participation by a wider scientific audience. The CSP is also looking at
+widening its membership at large in the astronomical community. The IVOA
+Education Interest Group is also looking at a new format, to both present a
+strong IVOA representation with external bodies (including the IAU), and to
+strengthen world-wide representation by including regional coordinators.

+### Scientific Tutorials
+
+A comprehensive list of scientific usage tutorials is maintained and updated by
+the [Euro-VO](http://www.euro-vo.org/) at the following
+[page](http://www.euro-vo.org/?q=science/scientific-tutorials). Each tutorial
+takes the user step-by-step through an example scientific use case using one or
+a number of [virtual observatory tools](http://www.euro-vo.org/?q=science/software)
+(e.g. TOPCAT, Aladin, the CDS Portal, VOSA, CASSIS, ...). Scientific use cases
+range from general data mining of objects, exploring Gaia data, determining
+stellar physical parameters, discovering brown dwarfs, to handling
+gravitational-wave sky maps for follow-up observations, and accessing and
+handling big datasets with the Astronomical Data Query Language (ADQL). Many of
+the tutorials have recently been updated in preparation for the
+[ASTERICS](https://www.asterics2020.eu/) schools.

+### Solar System in the VO
+
+Solar System sciences are now officially part of the VO. During the last Interop
+Meeting in Shanghai (China), the IVOA (International Virtual Observation
+Alliance) Exec committee approved the creation of a Solar System Interest Group
+within the IVOA. Some IVOA standards, protocols and tools are already used for
+solar and planetary sciences for data description, sharing and publishing. With
+this interest group, we will review and assess IVOA standards and propose
+adjustments when necessary. We will also work with large astronomical data
+centers to help them sharing solar and planetary (including exoplanets) data
+products more efficiently. This action is supported by the IPDA (International
+Planetary Data Alliance). The Europlanet/VESPA (Virtual European Solar and
+Planetary Access) project will also participate to the activities of this group.

+
+### Sherpa and Iris at the 229th AAS
+
+The Chandra X-Ray Observatory held a session on Flexible Multi-dimensional
+Modeling of Complex Data in Astronomy at the 229th meeting of the American
+Astronomical Society. The session used
+[Sherpa](http://cxc.cfa.harvard.edu/contrib/sherpa/), a Python based general
+modeling and fitting library for modeling multi-dimensional data, and
+[Iris](http://cxc.cfa.harvard.edu/iris), a VO-enabled spectral energy
+distribution analysis application built on top of Sherpa, as possible tools for
+accessing multi-wavelength data and interpreting the results.
+
+The workshop was broken into two parts: demonstrations, and "free time" for
+attendants to follow worksheets that guided using the tools in various science
+tasks. The Sherpa tutorial demonstrated basic-to-complex modeling scripts in
+Jupyter notebooks, and also highlighted
+[SABA](https://saba.readthedocs.io/en/latest/), a Python package that bridges
+Sherpa's modeling library to Astropy. The Iris demonstration focused on
+aggregating datasets from online data archives, from disk, and SAMP-enabled
+applications (via under-the-hood VO protocols), and data visualization and
+manipulation capabilities.
+
+Approximately 30 people attended the session, and a handful came to the Chandra
+booth after the meeting to learn more about using Sherpa and Iris for their
+science projects.

+### Tenth Spanish Virtual Observatory School
+
+The Spanish Virtual Observatory project held its tenth VO school at the
+Instituto de Astrofísica de Canarias, Spain, on 6-8 March 2017. The goal of the
+school was twofold: To expose participants to the variety of VO tools and
+services available today so that they can use them efficiently for their own
+research; and to gather requirements and feedback from them.
+
+Real life examples of scientific applications of VO tools and services were
+given. A large fraction of the time was dedicated to hands-on exercises, which
+allowed participants to become fully familiar with the VO capabilities on their
+own laptops.

+### Automatic composition of astrophysical services
+
+The semantic Web (Berneers-Lee et al. 2001) is an ongoing evolution of the
+current Web, based on algorithms and knowledge formalization allowing automatic
+reasoning about Web documents and services. CASAS (Composing Automatically and
+Semantically Astrophysical Services) is a tool that aims to bring the semantic
+web capabilities to astrophysical services, including VO and non-VO services,
+data providers and data processing alike. The Web interface of CASAS allows
+requesting a set of information to be retrieved from the services registered in
+the ontology underlying the system. The workflow leading to the requested
+information is then automatically composed, presented and may be run with the
+results automatically displayed. A more in-depth view of CASAS will be available
+in the next issue of the journal “Astronomy and computing” (DOI:
+). Response time for this first
+version may be long and the input parameters are restricted, which will be
+improved in future releases.

+### New version of CDS Portal
+
+CDS has released a new version of [the CDS Portal](http://cdsportal.unistra.fr/). It can be queried for an astronomical source or position, and aggregates in a single page a summary of results from various services, such as measurements and bibliography from SIMBAD, catalogues, tabular data and photometry from VizieR, images from Aladin and more.
+
+On the technical side, the new portal is built upon Javascript widgets querying the [MocServer](http://alasky.unistra.fr/MocServer/query) to quickly retrieve available datasets for the requested target. [Aladin Lite](http://aladin.unistra.fr/AladinLite/) is used to display data of interest ([HiPS (Hierarchical Progressive Surveys)](http://aladin.unistra.fr/hips/) images, catalogues, etc).
+
+The underlying technologies were presented at [the May 2016 IVOA meeting](http://wiki.ivoa.net/internal/IVOA/InterOpMay2016-Apps/Apps1-TBoch-HiPS-MOC-portal.pdf).

+Clusterix is a new tool jointly developed by the Spanish Virtual Observatory and
+the University of Barcelona (ICCUB-IEEC) whose goal is the determination of
+membership probabilities in stellar clusters from proper motion data. Using VO
+search protocols, the system also gathers parallaxes and radial velocities from
+different services and estimate physical parameters like effective temperatures
+and surface gravities using VO tools like VOSA. This information can be used to

+### ESASky: A science-driven discovery portal for space astronomy data
+
+[ESASky](http://sky.esa.int/) is the multi-mission archive interface developed
+at the ESAC Science Data Centre (ESDC) for exploration and discovery of the data
+kept in the ESA astronomical archives and archives from other data providers.
+Users can explore the sky in multiple wavelengths, quickly see the data
+available for their targets and retrieve the relevant science-ready products,
+with just a few clicks. The tool is completely web-based and it requires no
+prior knowledge of the specific details of each mission.
+
+ESASky features a sky exploration interface that uses AladinLite to visualise
+the HiPS of the different missions, as well as a single/multiple target
+interface. It is VO-compliant, allowing users to directly send their selected
+products via SAMP to an open VO application. The first version was released in
+May 2016, and it provided access to imaging and catalogue data. Later
+incremental releases added new functionalities and data. Future releases will
+enable retrieval of spectroscopic data and will incorporate features to allow
+the study of Solar System objects (SSO) and time-domain exploration. A beta
+version incorporating a prototype of the SSO search functionality with a limited
+number of 1000 asteroids is available at .

+
+We present RCSED, the value-added Reference Catalog of Spectral Energy
+Distributions of galaxies, which contains homogenized spectrophotometric data
+for 800,299 low- and intermediate-redshift galaxies (0.007 < z < 0.6) selected
+from the Sloan Digital Sky Survey spectroscopic sample. Accessible from the
+Virtual Observatory (VO) and complemented with detailed information on galaxy
+properties obtained with state-of-the-art data analysis, RCSED enables direct
+studies of galaxy formation and evolution over the last 5 Gyr. We provide
+tabulated color transformations for galaxies of different morphologies and
+luminosities, and analytic expressions for the red sequence shape in different
+colors. RCSED comprises integrated k-corrected photometry in up to 11
+ultraviolet, optical, and near-infrared bands published by the GALEX, SDSS, and
+UKIDSS wide-field imaging surveys; results of the stellar population fitting of
+SDSS spectra including best-fitting templates, velocity dispersions,
+parameterized star formation histories, and stellar metallicities computed for
+instantaneous starburst and exponentially declining star formation models;
+parametric and non-parametric emission line fluxes and profiles; and gas phase
+metallicities. We link RCSED to the Galaxy Zoo morphological classification and
+galaxy bulge+disk decomposition results of Simard et al. We construct the
+color-magnitude, Faber-Jackson, and mass-metallicity relations; compare them
+with the literature; and discuss systematic errors of the galaxy properties
+presented in our catalog. RCSED is accessible from the project web site and via
+VO simple spectrum access and table access services using VO-compliant
+applications. We describe several examples of SQL queries to the database.
+Finally, we briefly discuss existing and future scientific applications of RCSED
+and prospective catalog extensions to higher redshifts and different
+wavelengths.

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### The Santiago de Chile IVOA meeting
+
+Pepi Fabbiano, Mark Allen and Janet Evans
+
+The October IVOA Interoperability meeting took place in Santiago, Chile, 27-29
+October 2017. This was a short meeting, following the Santiago ADASS meeting,
+but enjoyed the greatest attendance so far, a record 151 attended, including a
+large cohort from Chile and other South American countries. This attendance
+highlights the increasing importance and presence of the VO and IVOA standards
+in astrophysical software.
+
+Although short, this meeting benefited from prior discussion during the ADASS
+meeting. It was characterized by high quality professional discourse and very
+good presentations. The Time Domain priority area was a focus, reflecting the
+increasing importance of survey and multi-messenger observations. Although no
+new standards were approved in this session, after the record 10 approved in the
+Spring Shanghai meeting, significant advances were achieved in the improvement
+of core IVOA standards, with updates to documents in the areas of Provenance,
+VODML, Grid and Web Services, DAL standards revisit, and Registry Interfaces.
+IVOA related activity included an interest in large data management and
+knowledge discovery, fostered by the IVOA KDD interest group, which sponsored a
+bird of a feather session in the ADASS meeting. The IVOA community is also
+responding to the needs of the astrophysical community at large, as evidenced by
+discussions and developments in notebooks, computing near the data, and focus on
+validation and monitoring of VO services.
+
+The overall theme from both ADASS and IVOA meetings was that the VO is
+everywhere!
+
+Thanks are due to the ChileVO organizing team, led by Dr. Mauricio Solar that
+made this meeting both enjoyable and productive.

+### IVOA Slack workspace
+
+During the IVOA Interop meeting in Santiago, Dave Morris launched a Slack
+workspace, , as an additional means for collaboration in
+the IVOA, writing: _"This is an experiment to see if Slack is a useful tool for
+IVOA members to communicate. To get it started, please invite your colleagues to
+join. If you are a member of a working group, please feel free to create a
+channel for it."_ IVOA on Slack is slowly getting traction, as there are already
+channels for GWS, KDD, Provenance, Registry, Time domain, Time series, VOEvent
+and general discussions.
+
+With new members needing an invitation to join a Slack workspace, one way to get
+an invitation is asking somebody active in one of the fields of work listed
+above, or else Dave Morris as the IVOA Slack workspace administrator.
+
+There exists also a well-functioning IRC gateway, accommodating users who prefer
+classical software for their on-line communication.

+### DAEPO BoF Session at ADASS
+
+On the recent ADASS conference held in Santiago, Chile, a birds of a feather
+(BoF) session on Data-driven and VO-enabled Education and Citizen Science was
+organized by the chair of IVOA Education Interest Group and IAU working group on
+Data Driven Astronomy Education and Public Outreach (DAEPO), Dr. ChenZhou Cui.
+In the BoF session, Ms. Janet Evans from the Harvard-Smithsonian Center for
+Astrophysics, Secretary of the Executive Committee of the IVOA, introduced the
+Virtual Observatory and the IVOA. The principal developer of the World Wide
+Telescope (WWT), Mr. Jonathan Fay from Microsoft Research, gave a talk on the
+history and latest development of WWT. Dr. Chenzhou Cui presented the work of
+China-VO in DAEPO with examples of a citizen science project called Popular
+Supernova Project (PSP) and interactive digital planetarium powered by WWT.
+Participants shared their experience and discussed how to efficiently leverage
+the data and VO-tools at hand to design and carry out education activities and
+citizen science projects.

+### Third ASTERICS Virtual Observatory School
+
+The [ASTERICS](http://asterics2020.eu/) project held its third VO school at the
+Centro de Astrobiología (INTA-CSIC), Madrid, on 14-16 November 2017. The goal of
+the school was twofold: to expose European astronomers and representatives of
+the
+[ESFRI](http://ec.europa.eu/research/infrastructures/index_en.cfm?page=esfri)
+projects involved in ASTERICS to the variety of VO tools and services available
+today so that they can use them efficiently for their own research; and to
+gather requirements and feedback from participants.
+
+During the first two days, VO experts gave hands-on sessions on the usage of VO tools and services using real life examples of scientific applications, which allowed participants to become fully familiar with the VO capabilities on their own laptops. The last day was then dedicated to the participants own science cases, applying what they had learnt earlier in the week.

+### GAVO-ArVO Collaboration Workshop
+
+Under joint funding by the Armenian Ministry of Education and Science (MES) and
+the German Bundesministerium für Bildung und Forschung (BMBF), a project on
+_building a high-performance research environment through German and Armenian
+Astrophysical Virtual Observatories_ (GAVO and ArVO) is being run, led by
+Joachim Wambsganss (German PI) and Areg Mickaelian (Armenian PI).
+
+The project started with a visit of eight Armenian scientists and students on
+23-30 November 2017, to Astronomisches Rechen-Institut – Universität Heidelberg
+(ARI, Heidelberg, Germany). The workshop introduced VO standards and tools, TAP,
+ADQL and the activities of GAVO to the Armenian team members. The second part of
+the Workshop was devoted to the implementation of VO tools on the Digitized
+First Byurakan Survey (DFBS), the main product of ArVO. The main task is the
+publication of the DFBS images and spectra through the VO, i.e. creating SIAP
+and SSAP services for the DFBS. Some scientific use cases were explored and
+discussed.
+
+The project will continue in 2018, when visits of German scientists and students
+to Armenia and more visits of Armenian scientists and students to Germany are
+planned. In addition, a workshop will be organised in Armenia, the 6th Byurakan
+International Summer School (6BISS), in September 2018, and will include VO
+tools training.

+
+### Aladin Desktop V10
+
+The Centre de Données astronomiques de Strasbourg (CDS) is pleased to announce a
+major release of Aladin Desktop v10.
+
+Aladin Desktop is an interactive sky atlas allowing an “all-sky” approach to the
+visualisation of astronomical data. Aladin V10 provides access to astronomical
+image surveys with capabilities for superimposing entries from astronomical
+catalogues or databases, and also providing access to related data and
+information from the SIMBAD database, the VizieR service and many other VO
+services.
+
+With a new modernized and simplified look and feel interface, the main
+innovation of Aladin v10 is the integration of the recent IVOA protocols (SIAv2,
+TAP, Datalink/SODA, RegTAP, MOC and HiPS) and some CDS advanced services such as
+the powerful CDS X-Match engine and the CDS database collection of sky coverage
+maps (MocServer). This evolution opens the door to new scientific use cases —
+fast browsing/filtering on all VO data collections, query by sky regions and/or
+by criteria, and transparent remote cross-matching with any tables are just a
+few examples of its new potentialities.
+
+The most visible improvement of Aladin v10 is the “Access Data Tree" panel
+directly available in the main window. This interactive tree enables easy
+manipulation and access to the 20,000 VO data sets compatible with Aladin
+including: All-sky image surveys, 3-d image cube surveys, catalogues, and
+spectra collections.

+
+### ESASky v2.0
+
+[ESASky](http://sky.esa.int/) is an open science discovery portal developed at
+the ESAC Science Data Centre (ESDC) for exploration and discovery of data hosted
+by the ESA astronomical archives and archives from other data providers. We are
+pleased to announce the release of ESASky version 2.0. This new version includes
+access to spectra from the Chandra, Herschel, HST, IUE, ISO and XMM-Newton
+missions; and a search mechanism for solar system objects (SSOs) imaged by HST,
+Herschel and XMM-Newton (targeted and serendipitous images). To achieve this,
+the ESASky team has created a pipeline that takes the ephemeris information of
+each SSO with respect to the position of each spacecraft using software by the
+IMCCE (Institute of Celestial Mechanica and Ephemeris Calculations), Paris and
+performs a crossmatch on the SSO orbits against the entire mission archives to
+find observations in which the SSO appears within the imaging instrument's field
+of view during the time the images were being taken.
+
+Finally, version 2.0 has a new and improved user interface, designed to improve
+the usability and user experience with ESASky. The new interface includes an
+improved representation of available data, with numbers and treemaps (rather
+than histograms); interactive footprints with the data panel; column filtering;
+centring on observations and sources; SSO orbits drawn on the sky; and a share
+button. Additionally, it is now possible to use ESASky in tablets and we now
+provide faster access to users outside Europe.

+### Introducing AAO Data Central
+
+We are pleased to introduce Data Central, the Australian Astronomical Observatory’s new data archive system. The system is planned to be the hub for all data from AAO-supported telescopes and surveys, including raw data and high-level science products. The system can be found at .
+
+Data Central is built upon Apache Hadoop infrastructure for data storage and uses PrestoDB as a query engine. Both these systems allow for distributed storage and querying; in particular, PrestoDB can query many different datastores, from all varieties of SQL to some noSQL systems such as MongoDB and Redis. This gives us tremendous flexibility when it comes to data access and interoperability.
+
+We currently host the GAMA DR2 and Panchromatic DR, the SAMI galaxy survey DR1, the GALAH stellar survey DR1, the DEVILS galaxy survey DR0 and the AAT raw data archive. There are around 15 other surveys and raw data archives to be included in the system in the next 12 to 18 months.
+
+Data Central currently offers the following services:
+
+- Query tool
+- Cone search
+- Image cutout
+- Spectrum viewer (coming soon)
+- New Single Object Viewer (coming soon)
+
+We also provide or will soon provide the following IVOA services:
+
+- TAP service —
+- Simple Cone Search (coming soon)
+- Simple Image Access (coming soon)
+- Simple Spectrum Access (coming soon)

+### Interoperable geographycally distributed VOSpaces
+
+A collaboration between the Trieste Astronomical Observatory of Italian National
+Institute of Astrophysics (OATs-INAF) and the Canadian Astronomy Data Center
+(CADC) of the National Research Council Canada, has taken a new step toward the
+global Virtual Observatory. A set of services based on IVOA standards and
+recommendations has been deployed using open-source available software
+( and ).
+Interoperability tests involving Authentication, Authorization, Data Access and
+Movement have been successfully concluded. A pre-production test-bed providing
+services accessibility in a cloud environment is available at OATs-INAF
+(). All the software used has been fully documented
+() offering the opportunity to replicate a similar set of
+services and to interoperate them with the already existing one. Specifically, a
+storage management solution, called vospace-backend, interfaced with the CADC
+VOSpace interface implementation, has been developed. It provides support for
+posix-based and OpenStack Swift storage solutions, but its plug-in architecture
+easily allows the support to other storage solutions with minimal development
+effort.

+
+### Solar Survey at Pic du Midi Observatory
+
+The CLIMSO solar survey started in 2007 and is expected to extend for many more
+years. All the data (images and films) can be downloaded from
+. This survey is done with four
+instruments (two coronagraphs and two solar refractors) that take images of the
+whole solar disc and prominences every minute (weather permitting), and the
+corona every hour. The Pic du Midi site in the French Pyrenees allows for a very
+good seeing and relatively frequent coronal skies.
+
+The covered spectral channels are :
+
+- whole solar disk at λ= 656.28nm Δλ=0.05nm (H-α), 15 cm refractor
+- solar prominences at λ= 656.28nm Δλ=0.25nm (H-α), 20 cm coronagraph
+- whole solar disk at λ= 393.3nm Δλ=0.25nm (Ca II), 9 cm refractor
+- solar prominences at λ= 1068.0nm Δλ=0.25nm (He I), 20 cm coronagraph
+- solar corona at λ= 1074.7nm Δλ=0.25nm (Fe XIII), 20 cm coronagraph
+
+The FITS images (2048*2048 pixels) are preprocessed and presented in a way that
+comply with the VO standards. They are calibrated in physical units for the
+whole disk images, and simply normalized for the prominences and corona images.

+
+### TOPCAT v4.5
+
+[TOPCAT](http://www.starlink.ac.uk/topcat/) is an interactive graphical desktop
+application for working with source catalogues and other tables. It provides VO
+access, crossmatching, visualisation and many other features. It comes with a
+sister application, [STILTS](http://www.starlink.ac.uk/stilts/), that lets you
+do all the same things from the command line. STILTS is very useful for
+scripting and reproducible work such as preparing plots for publication, but
+harder to learn than TOPCAT's point and click interface. The recent v4.5 release
+of TOPCAT has a
+[new control](http://www.starlink.ac.uk/topcat/sun253/StiltsControl.html) that
+displays the STILTS command to reproduce the current plot, either on the screen
+or to a graphics format like PNG or PDF. This lets you set up a plot
+interactively and then save the command for later scripting and adjustments.

+[Gaia TGAS search for Large Magellanic Cloud runaway supergiant stars. Candidate hypervelocity star discovery and the nature of R 71](http://adsabs.harvard.edu/abs/2017A%26A...603A..75L)
+**Lennon, Daniel J.; van der Marel, Roeland P.; Ramos Lerate, Mercedes; O'Mullane, William; Sahlmann, Johannes**
+_Astronomy and Astrophysics (2017) Vol. 228, Volume 603, A75_
+
+Aims: Our research aims to search for runaway stars in the Large Magellanic
+Cloud (LMC) among the bright Hipparcos supergiant stars included in the Gaia DR1
+Tycho-Gaia astrometric solution (TGAS) catalogue. Methods: We compute the space
+velocities of the visually brightest stars in the Large Magellanic Cloud that
+are included in the TGAS proper motion catalogue. This sample of 31 stars
+contains a luminous blue variable (LBV), emission line stars, blue and yellow
+supergiants, and an SgB[e] star. We combine these results with published radial
+velocities to derive their space velocities, and by comparing with predictions
+from stellar dynamical models we obtain each star's (peculiar) velocity relative
+to its local stellar environment. Results: Two of the 31 stars have unusually
+high proper motions. Of the remaining 29 stars we find that most objects in this
+sample have velocities that are inconsistent with a runaway nature, being in
+very good agreement with model predictions of a circularly rotating disk model.
+Indeed the excellent fit to the model implies that the TGAS uncertainty
+estimates are likely overestimated. The fastest outliers in this subsample
+contain the LBV R 71 and a few other well known emission line objects though in
+no case do we derive velocities consistent with fast (100 km s{{< sup -1 >}})
+runaways. On the contrary our results imply that R 71 in particular has a
+moderate deviation from the local stellar velocity field (40 km s{{< sup -1 >}})
+lending support to the proposition that this object cannot have evolved as a
+normal single star since it lies too far from massive star forming complexes to
+have arrived at its current position during its lifetime. Our findings therefore
+strengthen the case for this LBV being the result of binary evolution. Of the
+two stars with unusually high proper motions we find that one, the isolated
+B1.5 Ia{{< sup "\+" >}} supergiant Sk-67 2 (HIP 22237), is a candidate
+hypervelocity star, the TGAS proper motion implying a very large peculiar
+transverse velocity (360 km s{{< sup -1 >}}) directed radially away from the LMC
+centre. If confirmed, for example by Gaia Data Release 2, it would imply that
+this massive supergiant, on the periphery of the LMC, is leaving the galaxy
+where it will explode as a supernova.

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### Gaia DR2 and the VO: A two-way success story
+
+When, on 25th April at 12:00 sharp, thousands of astronomers opened TOPCAT,
+searched for “Gaia DR2” and found four services (ARI, CDS, ESA, GAVO) willing to
+answer significantly complex queries over the impressive 1.7 billion source
+catalogue, very few were aware that perhaps the most intensive and decisive
+operational test since the formation of the VO in 2002 was running at that
+precise moment.
+
+And it was a successful test. The VO behaved as good technology should behave:
+transparent to the users whilst empowering them to perform scientific queries
+without noticing the complexity of the standards and technologies served behind
+the tools. These include writing queries in a common, open IVOA standard (ADQL;
+Astronomical Data Query Language), accepted by all services; sending data
+through interoperable applications with one click with SAMP (Simple Application
+Mesaging Protocol); saving and sharing data through VOSpace services; and data
+distribution through DataLink.
+
+As well as using [TOPCAT](http://www.star.bris.ac.uk/~mbt/topcat/), many users
+decided to use the
+[ESA Gaia Archive interface](http://archives.esac.esa.int/gaia), Partner Data
+Centres interfaces at:
+[Centre de Données astronomiques de Strasbourg (CDS)](http://cds.unistra.fr/gaia),
+[Astronomisches Rechen-Institut (ARI)](http://gaia.ari.uni-heidelberg.de/),
+[Leibniz-Institute for Astrophysics Potsdam (AIP)](https://gaia.aip.de/) and the
+[ASI Space Science Data Center (SSDC)](http://gaiaportal.asdc.asi.it/), other VO
+tools, or the specifically developed
+[Python Astroquery Gaia library](http://astroquery.readthedocs.io/en/latest/gaia/gaia.html).
+Usage numbers for the first week speak for themselves: 34000 users accessed the
+ESA Gaia Archive interface with peaks of 1700 new users per hour, over 5000
+users sending more than 1.5 million data analysis queries and a total data
+retrieval of 118 TB.
+
+The VO-orientation of the ESA Gaia archive and partner archives and services is
+the result of many years of involvement of ESA and the Gaia partner data centres
+in the IVOA, and of the contributions through the
+[Gaia Data Processing and Analysis Consortium (DPAC)](http://www.cosmos.esa.int/web/gaia/dpac)
+of many partners and experts. VO technologies are now "release proven" (i.e. can
+accept very large peak loads), combining reliability with functionality, and
+making them an attractive option for future missions and projects.

+### IVOA meeting in Victoria, BC, Canada
+
+The Northern Spring meeting of the IVOA took place in Victoria, BC, Canada,
+between 27 May and 1 June 2018. This meeting was hosted by the Canadian
+Astronomy Data Centre (CADC).
+
+In this meeting we had the first IVOA Hackathon, organized by the Data Model
+Working Group. This Hackathon provided useful feedback to the data modelers as
+well as informing the participants of available software tools. General
+consensus was that similar hands on sessions should become a standing feature of
+IVOA meetings.
+
+The IVOA Committee for Science Priorities organized a special session with
+representatives of the Astropy community, to foster increasing collaboration
+between Data Center/Archive data providers and the astronomy user community. The
+IVOA will make increasing use of GitHub for standards development, to make them
+more visible to astronomers at large. Development of Python software based on
+IVOA standards was also discussed.
+
+The IVOA will host a booth at the upcoming IAU meeting in Vienna. All are
+invited for discussions and demonstrations of tools and interfaces.

+### China-VO Alibaba Astronomy Party and LAMOST Spectrum Data Mining Competition
+
+China-VO has recently made some efforts to promote Information Technology and
+data mining in astronomy. On 10-11 April, China-VO and Alibaba Cloud jointly
+organized an astronomy party in the Alibaba Group headquarter in Hangzhou,
+China. The party aimed to connect astronomers with IT experts in industry and
+find partners to help with the technical issues in their research projects.
+Researchers from nine astronomy research institutes in different area of China
+participated in the party and brought about 40 astronomical research projects
+and technical requirements, e.g. FAST pulsar searches, exoplanet searches, etc.
+More than 50 volunteers from various divisions of the Alibaba group, who are
+keen on astronomy, joined the party. Online discussion groups have formed since
+the party on different technical aspects, including web crawlers, machine
+learning, engineering, and big data processing.
+
+From February to May 2018, an Algorithm Competition on spectral classification
+was organized by China-VO and Alibaba Cloud. Around 1000 people (over 800 teams)
+from the public have participated in the competition, applying machine learning
+techniques on LAMOST spectral datasets to automatically classify the spectra
+into stars, galaxies, quasars and unknowns. The winning team employs deep neural
+networks to solve the problem and achieves an overall macro-F1 score of 0.83.
+
+These activities are new attempts of China-VO in terms of bridging astronomers
+with the technical community and combining astronomy research with public
+science in ways that both astronomers and the general public could benefit from.

+### Chandra Source Catalog (CSC 2.0)
+
+The second major release of the Chandra Source Catalog (CSC 2.0) is approaching
+completion, and access to data that have completed processing is currently
+possible through the CSCview user interface. CSC 2.0 will roughly triple the
+size of the current version of the catalog to an estimated 375,000 X-ray
+detections, corresponding to ~315,000 unique X-ray sources on the sky. For each
+detected X-ray source, the catalog provides a detailed set of properties
+including the source position and associated position error ellipse, source
+extent, multi-band aperture photometry probability density functions, spectral
+fits using several source models, hardness ratios, and intra- and
+inter-observation temporal variability measures. All numerical measures have
+associated two-sided confidence intervals. In addition to tabular data, the
+catalog provides FITS data products that are immediately suitable for further
+user analysis, including per-field and per-source images, source region
+polygons, photon event lists, responses, spectra, and light curves.
+
+Access to the version 1.1 release of the catalog is also possible through IVOA
+compliant SIAP, SCS, and TAP interfaces. Once version 2.0 is officially
+released, the new versions of the catalog will also be accessible through these
+interfaces.
+
+This work has been supported by NASA under contract NAS 8-03060 to the
+Smithsonian Astrophysical Observatory for operation of the Chandra X-ray Center.

+
+### Chandra adoption of Multi-Order Coverage maps (MOCs)
+
+As Chandra approaches its 20th year of operation, the total fraction of sky
+observed is nearing the 2.2% mark. A map showing the footprints of all Chandra
+public observations would resemble a large and sparse collection of isolated
+rectangular shapes, a few islands of closely and orderly positioned tiles and a
+patchwork of large, often connected regions, typically associated with
+structures in the nearby Universe.
+
+Now, such a map (and more) is available for everyone to admire and work with at
+ !
+
+In order to help astronomers interested in the coverage properties of Chandra
+data, the Chandra Data Archive (CDA) has recently generated and made available
+up-to-date Multi-Order Coverage maps (MOCs) of Chandra archival observations at
+different maximum spatial resolutions. These MOCs, described by the IVOA
+standard, combine the field-of-views of the distinct observations into a
+conveniently compressed global representation of their coverage. MOCs are
+optimized for interactive exploration but can also be used to filter lists of
+positions based on their positions relative to the Chandra footprint. Morever,
+MOCs make it easy to estimate the global properties of the Chandra coverage
+(i.e. total area), and apply boolean operators to the Chandra footprint and the
+footprints of other observations. These operations can be performed either via
+GUI tools such as TOPCAT and Aladin Desktop, or programmatically, using
+MOC-compatible libraries such as STILTS or Python libraries MOCPy and PyMOC.
+
+MOCs will complement the other Chandra data access interfaces and services by
+providing a novel representation of the geometric properties of the Chandra
+archival observations, thus making the X-ray Universe seen by Chandra more
+easily discoverable and explorable.

+### Gaia DR2 in CDS Services
+
+Gaia DR2 data are available since April 25th in CDS services: VizieR, Aladin,
+Sesame and the CDS cross-matching service.
+
+In addition to the
+[regular VizieR interface](http://vizier.u-strasbg.fr/viz-bin/VizieR?-source=I/345),
+VO access is provided through cone search queries and through TAP allowing the
+user to formulate SQL-like queries from our
+[web interface](http://tapvizier.u-strasbg.fr/adql/?I/345) or from any TAP
+client (Topcat or TAPHandle for instance). For power users, a command-line tool
+[find_gaia_dr2](http://cds.u-strasbg.fr/resources/doku.php?id=cdsclient:doc-find_gaia_dr2)
+allows users to query Gaia DR2 by position, source ID or by constraints on the
+parallax, proper motions, fluxes, etc.
+
+Aladin Desktop features a dedicated form for easy access to Gaia data and
+visualisation of proper motions.
+
+The cross-match service offers fast spatial cross-identifications of Gaia data
+with VizieR 18,000+ tables with positions or user-uploaded tables. Access to the
+cross-match is done either [via our web page](http://cdsxmatch.u-strasbg.fr/) or
+via Topcat.
+
+Gaia DR2 has also been made available as HiPS progressive catalogues, seamlessly
+browsable from Aladin Desktop and Aladin Lite as demonstrated here:
+, including a HiPS density
+map and a color flux map created by CDS from the Gaia catalogue.

+### HIPASS legacy data set now available through ASKAP’s new archive facility
+
+The CASDA team are pleased to announce that HIPASS cubes are now available in
+the CSIRO ASKAP Science Data Archive (CASDA).
+
+CASDA is a collaboration between CASS, CSIRO IM&T, and the Pawsey Supercomputing
+Centre, to build a data archive for the Australian Square Kilometre Array
+Pathfinder (ASKAP). It will provide long term storage for Australian SKA
+Pathfinder (ASKAP) data products, and serve those to astronomers around the
+world using both virtual observatory (VO) and web-based portal services.
+
+The `HI Parkes All Sky Survey' (HIPASS) is a legacy dataset of much interest and
+value to the community. The dataset covers the whole southern sky, and northern
+declinations to +25 deg. HIPASS was carried out from 1997 to 2002 with the
+Australia Telescope National Facility's Parkes 64-m telescope.
+
+CASDA provides full cube download, subcube and spectra cutout facilities
+utilizing the multi-dimensional VO protocols (SIA2, Datalink and SODA). You can
+access the HIPASS collection at:
+ or through CASDA’s VO
+interface. Please refer to the readme file attached to the collection for more

+
+### VOSA New Release and Gaia DR2
+
+The Spanish VO released a new version of VOSA (v6.0) in April 2018. VOSA (VO Sed
+Analyzer) is a web-based tool designed to build observational spectral energy
+distributions and to estimate physical parameters (Teff, logg, [M/H], masses,
+ages, etc) from comparison with models. In the last five years more than 1500
+users have analysed five million objects and have published more than 150
+refereed papers using VOSA.
+
+New photometric catalogues and collections of theoretical models, new
+visualization tools and an asynchronous management of the input files to avoid
+long waits with heavy files are some of the functionalities implemented in this
+new version.
+
+Special attention deserves to be given to the upgrades made to deal with Gaia
+DR2 data. Photometric information (G, Bp, Rp magnitudes) converted to fluxes
+using the SVO Filter Profile Service
+() as well as parallaxes can now be
+used in the VOSA workflow.

+**Venuti, L.; Prisinzano, L.; Sacco, G. G.; Flaccomio, E.; Bonito, R.; Damiani, F.; Micela, G.; Guarcello, M. G.; Randich, S.; Stauffer, J. R.; Cody, A. M.; Jeffries, R. D.; Alencar, S. H.

+_Astronomy and Astrophysics (2018) Volume 609, A10_
+
+Context. Reconstructing the structure and history of young clusters is pivotal
+to understanding the mechanisms and timescales of early stellar evolution and
+planet formation. Recent studies suggest that star clusters often exhibit a
+hierarchical structure, possibly resulting from several star formation episodes
+occurring sequentially rather than a monolithic cloud collapse.
+
+Aims: We aim to explore the structure of the open cluster and star-forming
+region NGC 2264 ( 3 Myr), which is one of the youngest, richest and most
+accessible star clusters in the local spiral arm of our Galaxy; we link the
+spatial distribution of cluster members to other stellar properties such as age
+and evolutionary stage to probe the star formation history within the region.
+
+Methods: We combined spectroscopic data obtained as part of the Gaia-ESO Survey
+(GES) with multi-wavelength photometric data from the Coordinated Synoptic
+Investigation of NGC 2264 (CSI 2264) campaign. We examined a sample of 655
+cluster members, with masses between 0.2 and 1.8 M☉ and including both
+disk-bearing and disk-free young stars. We used Teff estimates from GES and
+g,r,i photometry from CSI 2264 to derive individual extinction and stellar
+parameters.
+
+Results: We find a significant age spread of 4-5 Myr among cluster members.
+Disk-bearing objects are statistically associated with younger isochronal ages
+than disk-free sources. The cluster has a hierarchical structure, with two main
+blocks along its latitudinal extension. The northern half develops around the
+O-type binary star S Mon; the southern half, close to the tip of the Cone
+Nebula, contains the most embedded regions of NGC 2264, populated mainly by
+objects with disks and ongoing accretion. The median ages of objects at
+different locations within the cluster, and the spatial distribution of disked
+and non-disked sources, suggest that star formation began in the north of the
+cluster, over 5 Myr ago, and was ignited in its southern region a few Myr later.
+Star formation is likely still ongoing in the most embedded regions of the
+cluster, while the outer regions host a widespread population of more evolved
+objects; these may be the result of an earlier star formation episode followed
+by outward migration on timescales of a few Myr. We find a detectable lag
+between the typical age of disk-bearing objects and that of accreting objects in
+the inner regions of NGC 2264: the first tend to be older than the second, but
+younger than disk-free sources at similar locations within the cluster. This
+supports earlier findings that the characteristic timescales of disk accretion
+are shorter than those of disk dispersal, and smaller than the average age of
+NGC 2264 (i.e., ≲3 Myr). At the same time, we note that disks in the north of
+the cluster tend to be shorter-lived ( 2.5 Myr) than elsewhere; this may reflect
+the impact of massive stars within the region (notably S Mon), that trigger
+rapid disk dispersal.
+
+Conclusions: Our results, consistent with earlier studies on NGC 2264 and other
+young clusters, support the idea of a star formation process that takes place
+sequentially over a prolonged span in a given region. A complete understanding
+of the dynamics of formation and evolution of star clusters requires accurate
+astrometric and kinematic characterization of its population; significant
+advance in this field is foreseen in the upcoming years thanks to the ongoing
+Gaia mission, coupled with extensive ground-based surveys like GES.

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and
+upcoming events.

+
+### College Park IVOA Interoperability Meeting
+
+The Northern Fall IVOA Interoperability Meeting was held on November 8-10, 2018
+in College Park, Maryland, USA, supported by the NASA Astronomical Virtual
+Observatories (NAVO) and the US Virtual Observatory Alliance (USVOA). There were
+109 registered participants who gathered for two and a half days of productive
+discussions.
+
+The Working Group and Interest Group sessions covered scientific and
+technological aspects of interoperability of astronomy data and services. Many
+presentations reported on practical implementations of IVOA standards, showing
+results and providing feedback. Progress was reported on the ‘Time Domain’
+priority area. A number of contributions focussed on emerging needs of the
+astronomy community such as standards to support multi-messenger astronomy, and
+improving the access to VO resources via python language tools. Other topics
+included the status of operations in ‘VO weather reports’ and the use of Digital
+Object Identifiers (DOIs) for data and queries.
+
+As usual for ‘IVOA Interops’ held at this time of year, the meeting was
+connected to the ADASS conference. For a change, and partly due to a local
+football match, this Interop was held before ADASS. VO topics were prominent at
+ADASS, including two hands-on tutorials on the use of VO technologies (see under
+"Schools and Workshops"), an invited talk on Time Domain Astronomy by the IVOA
+Time Domain Interest Group chair, a talk on ‘Astropy and the VO’ and various
+demonstration booths highlighting VO access to data.
+
+Warm thanks to the local organisers lead by NAVO and USVOA! Mark your calendars
+for the next IVOA Interoperability Meeting in Paris, France, May 12-17, 2019.

+
+### Fourth ASTERICS Virtual Observatory School
+
+The [ASTERICS](http://asterics2020.eu/) project held its fourth VO school at the
+Centre de Données astronomiques de Strasbourg (CDS) in Strasbourg on 20-22
+November 2018. The goal of the school was twofold: (1) to expose European
+astronomers and representatives of the
+[ESFRI](http://ec.europa.eu/research/infrastructures/index_en.cfm?page=esfri)
+projects involved in ASTERICS to the variety of VO tools and services available
+today so that they can use them efficiently for their own research, and (2) to
+gather requirements and feedback from participants.
+
+During the first two days, VO experts gave hands-on sessions on the usage of VO
+tools and services using real life examples of scientific applications, which
+allowed participants to become fully familiar with the VO capabilities on their
+own laptops. The last day was then dedicated to the participants own science
+cases, applying what they had learnt earlier in the week.

+### Tutorials during ADASS 2018
+
+Two VO-related tutorials were given on Sunday, 11 November 2018 during the last
+ADASS meeting in College Park, USA. During each of the 2 hours session,
+participants familiarized themselves with different VO standards and tools.
+
+In [Tutorial T1, "All-sky astronomy with HiPS and MOCs"](http://cds.unistra.fr/adass2018/)
+conducted by Sebastien Derriere, the goal was to create image and catalogue
+HiPS, learn how to compare them to reference datasets, and share them in a web
+page. Advanced usage with the Table Access Protocol and the Astropy/MOCPy
+libraries was also shown.
+
+In [Tutorial T3, "A comprehensive use case scenario of VO standards and protocols"](http://www.g-vo.org/pmwiki/VOWorkshop/VOtutorialADASS2018)
+conducted by Hendrik Heinl, participants were introduced to the usage of some VO
+standards and how one can remotely crossmatch between different services and
+surveys. This was applied to identifying brown dwarves in 2MASS and SDSS.

+
+Double detonations in double white dwarf (WD) binaries undergoing unstable mass
+transfer have emerged in recent years as one of the most promising Type Ia
+supernova (SN Ia) progenitor scenarios. One potential outcome of this
+“dynamically driven double-degenerate double-detonation” (D6) scenario is that
+the companion WD survives the explosion and is flung away with a velocity equal
+to its >1000 km s−1 pre-SN orbital velocity. We perform a search for these
+hypervelocity runaway WDs using Gaia's second data release. In this paper, we
+discuss seven candidates followed up with ground-based instruments. Three
+sources are likely to be some of the fastest known stars in the Milky Way, with
+total Galactocentric velocities between 1000 and 3000 km s−1, and are consistent
+with having previously been companion WDs in pre-SN Ia systems. However,
+although the radial velocity of one of the stars is >1000 km s−1, the radial
+velocities of the other two stars are puzzlingly consistent with 0. The combined
+five-parameter astrometric solutions from Gaia and radial velocities from
+follow-up spectra yield tentative 6D confirmation of the D6 scenario. The past
+position of one of these stars places it within a faint, old SN remnant, further
+strengthening the interpretation of these candidates as hypervelocity runaways
+from binary systems that underwent SNe Ia.

+### What is the VO?
+
+The Virtual Observatory (VO) aims to provide a research environment that will
+open up new possibilities for scientific research based on data discovery,
+efficient data access, and interoperability. The vision is of global astronomy
+archives connected via the VO to form a multiwavelength digital sky that can be
+searched, visualized, and analyzed in new and innovative ways. VO projects
+worldwide working toward this vision are already providing science capabilities
+with new tools and services. This newsletter, aimed at astronomers, highlights
+VO tools and technologies for doing astronomy research, recent papers, and

+
+### IVOA Interoperability meeting in Paris, France
+
+The Northern Spring meeting of the IVOA took place in Paris, France at the Paris
+Observatory between 12-17 May 2019. The meeting was hosted by the
+[Paris Astronomical Data Centre](https://padc.obspm.fr/) and
+[Observatoire Virtuel France (OV-France)](http://www.france-ov.org/), and
+gathered 131 participants from around the world for a full schedule of events
+covering many aspects of the development and use of the Virtual Observatory.
+
+The Interop was centred around the sessions of the IVOA Working- and
+Interest-Groups which are the essential face-to-face working meetings of these
+groups for the development of IVOA standards, and also for reporting of feedback
+from implementations.
+
+The IVOA Committee for Science Priorities organized a Focus Session on Big Data
+Challenges where representatives from LSST, SKA, MAST and the ESA Gaia and
+Euclid missions outlined their data exploitation plans. The presentations and
+discussions showed that VO compliance is well integrated into their plans, and
+that the development of science analysis platforms is a strong common theme.
+
+A special ‘experimental’ event at this Interop was the Astropy-VO
+Sprint/Hackathon which gathered participants from the Astropy project and VO
+projects to work together on specific improvements to the interoperability of
+the VO within Astropy, and as a way to build stronger connections between VO and
+Astropy.
+
+A plenary session of the Solar System Interest Group welcomed the participation
+of representatives from the IPDA (International Planetary Data Alliance) and
+also new participation from Solar Physics projects. The International
+Planetarium Society made a plenary presentation, and other new participants
+included a representative from EUDAT.
+
+Many thanks are due to the local organisers (lead by Baptise Cecconi and Pierre
+Le Sidaner), and to sponsors Europlanet, the French Space Agency (CNES) and
+CNRS-INSU/ASOV. Furthermore the effort by the organisers to minimise the
+environmental impact via use of reusable/recyclable materials and a local
+sustainable procurement was highly appreciated.

+
+### XIII Spanish Virtual Observatory School
+
+The Spanish Virtual Observatory held their 13th VO School at the Complutense
+University of Madrid in Madrid on 4-5 March 2019. The goal of the school was
+twofold: (1) to expose participants to the variety of VO tools and services
+available today so that they can use them efficiently for their own research,
+and (2) to gather requirements and feedback from participants.
+
+To achieve these goals, VO experts lectured and tutored the participants on the
+usage of VO tools and services. Real life examples of scientific applications
+were given. A large fraction of the time was dedicated to hands-on exercises,
+which allowed participants to become fully familiar with the VO capabilities on
+their own laptops.

+
+### Creating High Quality HiPS Visualizations With Montage
+
+Version 5 of the Montage image mosaic engine provided support for the HEALPix
+sky tesselation scheme. Extending this capability to support HiPS, which is
+based on HEALPix, is an obvious development for Montage. We provide here a
+status report on a collaboration with IRSA to use Montage to create HiPS maps of
+all four bands of the WISE all-sky survey, down to HiPS level 9 tiles, level 18
+pixels. The maps are scheduled for completion and release in late-Summer 2019.
+
+There are two characteristics of Montage that bring value to HiPS maps: it
+rectifies backgrounds by modeling differences between images; and includes an
+adaptive stretch for creating visualizations. Creating a HiPS map of the WISE
+images involves using existing tools to computing HEALPix mosaics of the WISE
+images in FITS format, background rectified to create the highest quality
+mosaics, and then creating from the mosaics HiPS tiles in PNG format, with
+display values created with an adaptive stretch; the process used new tools that
+will be released in Summer 2019. Thus far we have begin created HiPS tiles for
+18% of the sky, and we have begun processing the rest of the WISE images.

+
+### Exo-MerCat, a VO-aware exoplanet catalog
+
+After attending the fourth VO school at the Centre de Données astronomiques de
+Strasbourg (CDS) in Strasbourg on 20-22 November 2018, the construction of an
+exoplanet catalog was finalized that collects all available data from the
+currently available online databases, called Exo-MerCat. Exo-MerCat is a Python
+code that collects and selects the most precise measurement for all interesting
+planetary and orbital parameters, taking into account the presence of multiple
+aliases for the same target. It performs comparisons and checks as well, to find
+coordinate errors or alias mismatches. By means of VO TAP and ConeSearch queries
+to SIMBAD and VizieR, it retrieves the main identifier for each target, allowing
+any user to easily download stellar information at a later stage by querying
+their favorite catalog in a standardized VO-aware way. For each interesting
+planetary parameter, Exo-MerCat stores the corresponding reference paper link.
+
+A Graphic User Interface is provided, which allows the selection of all sorts of
+parameter ranges. It can also generate automatic plots that are commonly used in
+the exoplanetary community, and the user can retrieve and manipulate data at
+will. Exo-MerCat is ingested into a database with a TAP service and can be
+queried by all the VO-aware TAP-enabled applications.
+
+The software was presented at the Paris InterOp Meeting
+(). All
+further information will be published soon in a peer-reviewed paper (Alei et al.
+– submitted).

+
+### LAMOST Releases the Fifth Data Release (DR5) Internationally
+
+LAMOST published its fifth Data Release (DR5) to astronomers worldwide on June
+26, 2019, according to the international astronomical practice and "the LAMOST
+Spectral Survey Data Policy". It includes all spectra obtained during the pilot
+survey and the first five years' regular survey. Scientific users can log on to
+the website powered by the China-VO at for data query
+and download. The data release complies with multiple IVOA standards and
+protocols, including Simple Cone Search, Simple Spectral Access (SSA), Simple
+Application Messaging Protocol (SAMP), etc.
+
+Through LAMOST DR5, a total number of 9.02 million spectra were released to the
+international community. Additionally, a catalog which provides stellar
+parameters of 5.34 million stars was also released internationally in this data
+set. The catalog will also be included in CDS VizieR. LAMOST DR5 has thus
+resulted in the largest public spectral data set and stellar parameter catalog
+in the world at present!

+### pyESASky: An ESASky widget for Jupyter
+
+[ESASky](https://sky.esa.int/) allows scientists to explore large collections of
+astronomical data with the click of a button. At the same time,
+[Jupyter Notebook](https://jupyter.org/) and, more recently, JupyterLab provide
+the framework for quick and effective manipulation, visualisation and analysis
+of datasets. To take advantage of both tools, at the
+[ESAC Science Data Centre (ESDC)](https://archives.esac.esa.int/) we have
+developed pyESASky, a Jupyter Widget for ESASky. This is a library that allows
+scientists to interact with ESASky within Jupyter, and to overlay their own data
+on ESASky, from catalogues to footprints and HiPS.
+
+The library, still a beta version, can be obtained from
+[GitHub](https://github.com/esdc-esac-esa-int/pyesasky). Installation
+instructions and some sample notebooks are also included in this distribution.
+Interested users are invited to test the widget and provide us feedback via the

+[The CARMENES search for exoplanets around M dwarfs. Different roads to radii and masses of the target stars](https://ui.adsabs.harvard.edu/abs/2019A%26A...625A..68S/abstract)
+**Schweitzer, A.; Passegger, V. M.; Cifuentes, C.; Béjar, V. J. S.; Cortés-Contreras, M.; Caballero, J. A.; del Burgo, C.; Czesla, S.; Kürster, M.; Montes, D.; Zapatero Osorio, M.

+_A&A (2019) Volume 625, 68_
+
+Aims: We determine the radii and masses of 293 nearby, bright M dwarfs of the
+CARMENES survey. This is the first time that such a large and homogeneous
+high-resolution (R > 80 000) spectroscopic survey has been used to derive these
+fundamental stellar parameters.
+
+Methods: We derived the radii using Stefan-Boltzmann's law. We obtained the
+required effective temperatures Teff from a spectral analysis and we obtained
+the required luminosities L from integrated broadband photometry together with
+the Gaia DR2 parallaxes. The mass was then determined using a mass-radius
+relation that we derived from eclipsing binaries known in the literature. We
+compared this method with three other methods: (1) We calculated the mass from
+the radius and the surface gravity log g, which was obtained from the same
+spectral analysis as Teff. (2) We used a widely used infrared mass-magnitude
+relation. (3) We used a Bayesian approach to infer stellar parameters from the
+comparison of the absolute magnitudes and colors of our targets with
+evolutionary models.
+
+Results: Between spectral types M0 V and M7 V our radii cover the range 0.1 R ⊙
+< R < 0.6 R ⊙ with an error of 2-3% and our masses cover 0.09 ℳ⊙ < ℳ < 0.6 ℳ⊙
+with an error of 3-5%. We find good agreement between the masses determined with
+these different methods for most of our targets. Only the masses of very young
+objects show discrepancies. This can be well explained with the assumptions that
+we used for our methods.

+
+### The Northern Spring Interoperability Meeting
+
+Janet Evans and Patrick Dowler
+
+The Northern Spring Interop meeting was held May 4–8 virtually via Zoom. Like
+many other conferences caught in the pandemic, the meeting originally scheduled
+for Sydney Australia was quickly re-organized. A virtual meeting seemed
+appropriate for an organization that has ‘Virtual’ in its name – so we set forth
+to meet the challenge! A surprising outcome was that this year’s Northern Spring
+Interop meeting had the largest number of attendees, at 207, of any IVOA meeting
+previously. Many participants attended sessions of interest with an average of
+~50 attendees at each session.
+
+At registration, participants were given the opportunity to ‘vote’ on topics of
+interest. The most popular topics made up approximately half of the program. The
+other half of the sessions focused on core topics related to status and
+discussion on current technical coordination group efforts.
+
+The meeting format included serial sessions during three time slots, arranged so
+that two of the sessions could easily be attended for 2/3 of the world-wide
+participants in a given day, while the third session would fall somewhere during
+the overnight hours. Each session had a presenter, a moderator and a note-taker.
+The Zoom ‘chat’ and ‘raised hand’ features were used to take questions. Etherpad
+was used for notes and added questions from the audience. Each session was 60
+minutes and video recorded for convenient access to meeting content.
+
+Highlights of the meeting included a Radio Astronomy Plenary. The Radio
+Astronomy interest group is a new group within the IVOA and presentations
+highlighted a number of projects that are making use of the VO in their current
+work and identified some areas of further work that are needed going forward.
+The FAIR Data Maturity Model presentation and discussion in the IVOA drew
+considerable interest and is core to many of our discussion about data handling.
+The Working and Interest groups provided status updates in their sessions on
+ongoing efforts. Each session fielded questions and engaged in discussions with
+the audience. Included was a Data Model status on the Source data model, and the
+Measurements, Coordinates, and Transform models. The Data Access Layer (DAL)
+group updated the attendees on current efforts including DataLink, ADQL, SIA2
+and SODA. The Timing interest group engaged in several joint sessions with other
+groups and covered topics including light curves in VOTables, VOevent next
+steps, Cone search, and an update on the working standard that identifies
+Observatory object visibility and schedule for joint and follow-up observations
+at other facilities. The Grid and Web Services group held sessions on
+Standardizing Science Platforms and moving toward a new single sign-on standard
+able to allow applications and services to easily access private data. Other
+interesting sessions focused on Python based tools and applications,
+Vocabularies in the VO, and an instructional ‘How To’ session using Git to edit
+and build a VO document. Further information on these topics is available from
+the [Interop program page](https://wiki.ivoa.net/twiki/bin/view/IVOA/InterOpMay2020).
+
+The IVOA meeting did miss the hallway chats and working tag-ups that many
+members find valuable in moving efforts forward. There were no coffee breaks,
+lunches or dinners together where team bonding and coordination also take place.
+However, we were encouraged by the number of attendees, and we learned that we
+reached people who would otherwise not travel to a meeting. Many familiar faces
+and new friends met in this virtual environment for 5 days. Our plan forward is
+to work to find the balance between the traditional meeting and virtual
+meetings. We thank all who participated in the first Virtual Interop meeting and
+encourage you to continue to participate in the efforts of the IVOA through the
+[working group and interest group email discussions](http://www.ivoa.net/members/index.html)
+and engaging with the IVOA.

+### Aladin V11
+
+The CDS is pleased to announce the 11th release of its Aladin Desktop software
+on April 2020.
+
+Aladin Desktop is an interactive sky atlas allowing an “all-sky” approach to the
+visualisation of astronomical data. Aladin provides access to astronomical image
+surveys with capabilities for superimposing entries from astronomical catalogues
+or databases, and also providing access to related data and information from the
+SIMBAD database, the VizieR service and many other VO services.
+
+The main innovation of Aladin v11 is the support of the temporal dimension of
+data collections, whether for filtering catalog sources, or for handling time
+coverages. This new version also includes support for the most recent IVOA
+standards, including TAP1.1 (s_region definition), MOC1.1 (ASCII serialization)
+and VOTable 1.4 (TIMESYS support). The new compression modes described in
+version 4.0 of the FITS reference document are also now supported (RICE, GZIP_1,
+GZIP_2, HCOMPRESS ...).

+
+[MASCARA-4 b/bRing-1 b: A retrograde hot Jupiter around a bright A-type star](https://ui.adsabs.harvard.edu/abs/2020A%26A...635A..60D/abstract)
+**Dorval, P.; Talens, G. J. J.; Otten, G. P. P. L.; Brahm, R.; Jordán, A.; Torres, P.; Vanzi, L.; Zapata, A.; Henry, T.; Paredes, L.; Jao, W. C.; James, H.; Hinojosa, R.; Bakos, G.

+_A&A (2020) Volume 635, A60_
+
+
+_Context._ The Multi-site All-Sky CAmeRA (MASCARA) and bRing are both
+photometric ground-based instruments with multiple stations that rely on
+interline charge-coupled devices with wide-field lenses to monitor bright stars
+in the local sky for variability. MASCARA has already discovered several planets
+in the northern sky, which are among the brightest known transiting hot Jupiter
+systems.
+
+_Aims._ In this paper, we aim to characterize a transiting planetary candidate
+in the southern skies found in the combined MASCARA and bRing data sets of HD
+85628, an A7V star of V = 8.2 mag at a distance 172 pc, to establish its
+planetary nature.
+
+_Methods._ The candidate was originally detected in data obtained jointly with
+the MASCARA and bRing instruments using a Box Least-Square search for transit
+events. Further photometry was taken by the 0.7 m Chilean-Hungarian Automated
+Telescope (CHAT), and radial velocity measurements with the Fiber Dual Echelle
+Optical Spectrograph on the European Southern Observatory 1.0 m Telescope.
+High-resolution spectra during a transit were taken with the CTIO
+high-resolution spectrometer (CHIRON) on the Small and Moderate Aperture
+Research Telescope System 1.5 m telescope to target the Doppler shadow of the
+candidate.
+
+_Results._ We confirm the existence of a hot Jupiter transiting the bright A7V
+star HD 85628, which we co-designate as MASCARA-4b and bRing-1b. It is in an
+orbit of 2.824 days, with an estimated planet radius of 1.53−0.04+0.07 RJup and
+an estimated planet mass of 3.1 ± 0.9 MJup, putting it well within the planetary
+regime. The CHAT observations show a partial transit, reducing the probability
+that the transit was around a faint background star. The CHIRON observations
+show a clear Doppler shadow, implying that the transiting object is in a
+retrograde orbit with |λ| =244.9−3.6+2.7°. The planet orbits at a distance of
+0.047 ± 0.004 AU from the star and has a zero-albedo equilibrium temperature of
+2100 ± 100 K. In addition, we find that HD 85628 has a previously unreported
+stellar companion star in the Gaia DR2 data demonstrating common proper motion
+and parallax at 4.3′′ separation (projected separation ~740 AU), and with
+absolute magnitude consistent with being a K/M dwarf.
+
+_Conclusions._ MASCARA-4 b/bRing-1 b is the brightest transiting hot Jupiter
+known to date in a retrograde orbit. It further confirms that planets in
+near-polar and retrograde orbits are more common around early-type stars. Due to
+its high apparent brightness and short orbital period, the system is
+particularly well suited for further atmospheric characterization.

+### Northern Fall Interoperability Meeting Overview
+
+Janet Evans and Patrick Dowler
+
+The Northern Fall Interop meeting was held Nov 17-19, 2020 via Zoom with 213
+registered participants from all around the globe. The meeting organization was
+similar to that of our May Interop virtual meeting. We used Zoom as our shared
+remote service, and Etherpad for live notes and questions. We kept presentations
+to a single thread (no parallel sessions) and saved a good amount of the time
+for input and discussion. Sessions were recorded and posted so that if you
+missed a session you can go back and view it. Here is the link if you are
+interested in session videos:
+(). We worked to
+schedule sessions with reasonable times during the day for 2 of the 3 sessions a
+day in any one time zone.
+
+There was a call put out for community led presentations. The meeting web page
+supported abstract submission for presentation consideration. Contributions at
+this Interop were 10-12 minutes in length with additional time for Q&A. The
+other half of the sessions were led by the IVOA Working Groups (WG) and Interest
+Groups (IG) and focused on core topics related to status and discussion of
+current technical coordination group efforts. The community presentations were
+folded into WG/IG sessions and provided a nice balance between contributed and
+core topics.
+
+The Applications (Apps) WG focused on the software used to access VO services
+and data with presentations that included MOC 2.0 status, interoperability
+development in the AAS WWT, a VOTable topics review, and protocols for handling
+file-oriented catalog data. Data Access Layer (DAL) WG sessions focused on
+current efforts including DALI, ADQL, ConeSearch, DataLink, and ObsVisSAP. The
+audience was updated with the latest status, and attendees were invited to
+contribute and get involved. The DataModel (DM) WG sessions provided status of
+ongoing efforts including ObsLocTAP, MANGO – a model for Source Data, and the
+Measurements, Coordinates, and Transform models progress, along with ProvTAP
+feedback from the community. The Grid and Web Services (GWS) WG aims to define
+the use of grid technologies and web services within the VO context. The focus
+of their sessions were on authorization protocols and applications. In
+collaboration with the Theory IG, a session on science platforms was also
+hosted. The Registry WG with a focus on discoverability and bibliographical
+tracking for VO-compatible data and services, held a session that focused on
+upgrading the VO publishing registry. In addition, in a joint session with the
+Semantics Working Group, a discussion of the latest vocabularies were presented.
+The IVOA addresses a wide range of topics for interoperability that are aimed
+toward ease of data use for the astronomy community.
+
+The Closing Plenary and presentation from the TCG chair Pat Dowler, reminded the
+audience of the Technical Coordination Group (TCG) and their role in the IVOA.
+The TCG is made up of Chairs and Vice-Chairs of working groups, interest groups,
+and committees. They are tasked with building consensus in the WG and community,
+assure coordination between WG/IG & the Committee for Science Priorities (CSP),
+liaison with the IVOA executive committee, and support committee roles in the
+IVOA documents and standards process. TCG membership has a 3 year term with a
+possible 1 year extension. Members of the astronomical community are welcome to
+get involved in the IVOA and to consider a role in the TCG.

+### The Spanish Virtual Observatory Schools
+
+Miriam Cortés
+
+[The Spanish Virtual Observatory (SVO)](https://svo.cab.inta-csic.es/) has large
+experience organizing VO schools: 25 within the last eleven years at a national
+and international level.
+
+During the last months, and in the context of the pandemic situation, we have
+made a large effort to make these schools “virtual”. In November and December
+2020, three virtual schools were conducted: two of them as extracurricular
+courses for MSc students at the Universidad Complutense de Madrid and
+Universidad Autónoma de Madrid with 15-20 participants each (similar to previous
+editions), and a third one in partnership with the Sociedade Astronômica
+Brasileira (SAB) as a capaciting building program with around 60 participants.
+
+The platforms employed to carry out these schools were zoom and a Slack
+workspace. Also the whole programme was adapted to the constraints imposed by
+remote teaching. The experience gained as well as the positive feedback gathered
+from the participants have encouraged us to continue with this model aiming at
+reaching a broader audience.

+
+### Gaia Early Data Release 3 available through VO applications
+
+The Gaia Early Data Release 3 (EDR3) was successfully released on 3 December
+2020. Gaia EDR3 contains detailed information on more than 1.8 billion sources,
+detected by the Gaia spacecraft. This represents an increase of more than 100
+million sources over the previous data release (Gaia DR2), which was made public
+in April 2018. Gaia EDR3 also contains colour information for around 1.5 billion
+sources, an increase of about 200 million sources over Gaia DR2. As well as
+including more sources, the general accuracy and precision of the measurements
+has also improved.
+
+Gaia EDR3 data is available from the
+[ESA Gaia Archive](https://archives.esac.esa.int/gaia), from the Gaia partner
+data centres:
+[Centre de Données astronomiques de Strasbourg(CDS)](http://cds.unistra.fr/gaia),
+[ASI Space Science Data Center (SSDC)](https://gaia.ssdc.asi.it/),
+[Astronomisches Rechen-Institut (ARI)](http://gaia.ari.uni-heidelberg.de/) and
+[Institut für Astrophysik Potsdam (AIP)](https://gaia.aip.de/), from VO Tools
+such as [Aladin](https://aladin.u-strasbg.fr/AladinDesktop/),
+[TOPCAT](http://www.star.bris.ac.uk/~mbt/topcat/) and
+[VOSA](http://svo2.cab.inta-csic.es/svo/theory/vosa/), from VO enabled tools
+such as [ESASky](https://sky.esa.int/) and from the specifically developed
+[Python Astroquery Gaia module](http://astroquery.readthedocs.io/en/latest/gaia/gaia.html).
+
+The VO-orientation of the Gaia archive and partner archives and services is the
+result of many years of involvement of ESA and the Gaia partner data centres in
+the IVOA, and of the contributions through the
+[Gaia Data Processing and Analysis Consortium (DPAC)](http://www.cosmos.esa.int/web/gaia/dpac)
+of many partners and experts. As shown by Gaia DR2 and EDR3, VO technologies are
+now "release proven" (i.e. can accept very large peak loads) and combine
+reliability with functionality, making them an attractive option for future
+missions and projects.

+
+[Active deep learning method for the discovery of objects of interest in large spectroscopic surveys](https://ui.adsabs.harvard.edu/abs/2020A%26A...643A.122S/abstract)
+**Škoda, P.; Podsztavek, O.; Tvrdík, P.**
+_A&A (2020) Volume 643, A122_
+
+
+_Context._ Current archives of the LAMOST telescope contain millions of
+pipeline-processed spectra that have probably never been seen by human eyes.
+Most of the rare objects with interesting physical properties, however, can only
+be identified by visual analysis of their characteristic spectral features. A
+proper combination of interactive visualisation with modern machine learning
+techniques opens new ways to discover such objects.
+
+_Aims._ We apply active learning classification methods supported by deep
+convolutional neural networks to automatically identify complex emission-line
+shapes in multi-million spectra archives.
+
+_Methods._ We used the pool-based uncertainty sampling active learning method
+driven by a custom-designed deep convolutional neural network with 12 layers.
+The architecture of the network was inspired by VGGNet, AlexNet, and ZFNet, but
+it was adapted for operating on one-dimensional feature vectors. The unlabelled
+pool set is represented by 4.1 million spectra from the LAMOST data release 2
+survey. The initial training of the network was performed on a labelled set of
+about 13 000 spectra obtained in the 400 Å wide region around Hα by the 2 m
+Perek telescope of the Ondřejov observatory, which mostly contains spectra of Be
+and related early-type stars. The differences between the Ondřejov
+intermediate-resolution and the LAMOST low-resolution spectrographs were
+compensated for by Gaussian blurring and wavelength conversion.
+
+_Results._ After several iterations, the network was able to successfully
+identify emission-line stars with an error smaller than 6.5%. Using the
+technology of the Virtual Observatory to visualise the results, we discovered
+1013 spectra of 948 new candidates of emission-line objects in addition to 664
+spectra of 549 objects that are listed in SIMBAD and 2644 spectra of 2291
+objects identified in an earlier paper of a Chinese group led by Wen Hou. The
+most interesting objects with unusual spectral properties are discussed in
+detail.

+### Northern Fall Interoperability Meeting Overview
+
+Janet Evans, Marco Molinaro and Patrick Dowler
+
+The Northern Spring Interop meeting was held May 25-28, 2021 via Zoom with 256
+registered participants. New this year was a Newcomers session, and 2
+Mini-Workshops. The Newcomers session was sponsored by the Education Interest
+Group and held on May 24 – the day before the opening of the Interop. Several
+scientific use cases were demoed using VO-standards and protocols. The aim was
+to help newcomers understand the structure of the IVOA and how Interop meetings
+are organized in order to get the most out of the upcoming meeting.
+
+The first Mini-Workshop was on the use of Science Platforms for the
+dissemination of Cosmological Simulations. The workshop brought together
+scientists, experts in computational Cosmology, VO experts and SP developers who
+presented and discussed current implementations and ideas for their future
+development. The sessions were well attended with many contributions.
+
+The second Mini-Workshop was on Data Model Usage in the VO. In January, a
+collaborative process was initiated to illustrate how the VO can use models to
+facilitate interoperability when accessing and analyzing data. The outcome of
+this work served as a basis for presentations and discussions during the Data
+Model workshop with a focus on time series and catalog data. Follow-on
+discussions have been ongoing since the workshop with efforts toward a final
+mapping syntax and development of a roadmap planned for conclusion this summer.
+
+A community session was held on IVOA/Astropy/Astroquery/PyVO Collaborations
+where members of the IVOA, Astropy, and User community discussed topics and
+priorities for further joined priorities and efforts. Other sessions led by the
+IVOA Working and Interest Groups focused on core topics related to current
+Technical Coordination Group (TCG) efforts. Community led presentations provided
+a balance between contributed and core presentations. All sessions were recorded
+and available
+[here](https://www.canfar.net/storage/list/pdowler/ivoa/virtual2021a).

+### First "ESCAPE Science with interoperable data" school
+
+Enrique Solano, Miriam Cortés
+
+Following the long tradition of VO schools organised by the Euro-VO initiative
+in the framework of different European projects (AIDA, 2008-2010; ICE,
+2010-2012; CoSADIE, 2012-2015; and ASTERICS, 2015-2019) the ESCAPE project held
+its first VO school on 8-12, 19 February 2021. As in previous schools, the goal
+was twofold: to expose participants to the variety of VO tools and services so
+that they can use them efficiently for their own research, and to gather
+requirements and feedback from them. Participants were also introduced to the
+vision of the ESCAPE project, in particular to the new context of data sharing
+where the Virtual Observatory framework is being integrated into the European
+Open Science Cloud (EOSC).
+
+The school was planned to be held in Madrid in May 2020. However, due to the
+COVID-19 pandemic, it was postponed and held on-line on February 2021 using Zoom
+and Slack as platforms.
+
+During the school, VO experts gave hands-on sessions on the usage of VO tools
+and services using real life examples of scientific applications. These hands-on
+tutorials provided the starting point for participants to use the tools and
+services for their own science projects with the benefit of the expertise of the
+tutors.The hands-on tutorials and the more advanced presentations were aimed at
+addressing the needs of the participants based on the information they provided
+during the registration. The last day was dedicated to the participants own
+science cases, applying what they had learnt earlier in the week.
+
+The school was the first experience for many of the partners to run a
+high-level-interactive event in an on-line setting. Nevertheless, this
+challenging situation did not prevent the school from running very smoothly and
+in a perfect “virtual” atmosphere. The meeting was a success, with a great
+atmosphere favouring a lot of exchanges and discussions. 93% of the participants
+rated the school as “very good” or “excellent” while 100% of the participants
+foresee using VO-tools in their future research.
+

+IPAC, has over the past 18 months redesigned its infrastructure to make the data
+more standardized, easier to access, more complete, and better reflect the
+scientific progress of the field of exoplanetary astrophysics. As part of this
+effort, the Exoplanet Archive released new and more comprehensive tables that
+were underpinned by Python-based nexsciTAP server
+(). With the release of the new
+tables atop the new TAP services in 2020, the NASA Exoplanet Archive saw a
+noticeable increase in access of the tables by the community. The NASA Exoplanet
+Archive is now in the process of making all its tables TAP compliant.

+### VO standards-based Metadata Management and Data Submission System of NADC
+
+Yihan Tao
+
+The National Astronomical Data Center (NADC) of China has developed a metadata
+management and data submission system. Data preservation for research project is
+one of the major responsibilities for NADC.The system is aimed at supporting the
+data submission process of astronomical projects, including the submission and
+review of metadata and data. With the system, data administrators can also
+curate a published data catalogue and manage the metadata. The metadata standard
+employed in the system is consistent with and extended from the VO
+standards-Resource Metadata for the Virtual Observatory Version 1.12 and IVOA
+Observation Data Model Core Components and its Implementation in the Table
+Access Protocol. In order to describe and filter the dataset by types, a
+multifaceted taxonomy of waveband, telescope/project, subject, data product
+type, production age, process level, content type and content level is adopted
+in the system and displayed as tags.

+[Gaia Early Data Release 3. Summary of the contents and survey properties](https://ui.adsabs.harvard.edu/abs/2021A%26A...649A...1G/abstract)
+**Gaia Collaboration**
+_A&A (2021) Volume 649, A120_
+
+
+_Context._ We present the early installment of the third Gaia data release, Gaia
+EDR3, consisting of astrometry and photometry for 1.8 billion sources brighter
+than magnitude 21, complemented with the list of radial velocities from Gaia
+DR2.
+
+_Aims._ A summary of the contents of Gaia EDR3 is presented, accompanied by a
+discussion on the differences with respect to Gaia DR2 and an overview of the
+main limitations which are present in the survey. Recommendations are made on
+the responsible use of Gaia EDR3 results.
+
+_Methods._ The raw data collected with the Gaia instruments during the first 34
+months of the mission have been processed by the Gaia Data Processing and
+Analysis Consortium and turned into this early third data release, which
+represents a major advance with respect to Gaia DR2 in terms of astrometric and
+photometric precision, accuracy, and homogeneity.
+
+_Results._ Gaia EDR3 contains celestial positions and the apparent brightness in
+G for approximately 1.8 billion sources. For 1.5 billion of those sources,
+parallaxes, proper motions, and the (GBP − GRP) colour are also available. The
+passbands for G, GBP, and GRP are provided as part of the release. For ease of
+use, the 7 million radial velocities from Gaia DR2 are included in this release,
+after the removal of a small number of spurious values. New radial velocities
+will appear as part of Gaia DR3. Finally, Gaia EDR3 represents an updated
+materialisation of the celestial reference frame (CRF) in the optical, the
+Gaia-CRF3, which is based solely on extragalactic sources. The creation of the
+source list for Gaia EDR3 includes enhancements that make it more robust with
+respect to high proper motion stars, and the disturbing effects of spurious and
+partially resolved sources. The source list is largely the same as that for Gaia
+DR2, but it does feature new sources and there are some notable changes. The
+source list will not change for Gaia DR3. Conclusions: Gaia EDR3 represents a
+significant advance over Gaia DR2, with parallax precisions increased by 30 per
+cent, proper motion precisions increased by a factor of 2, and the systematic
+errors in the astrometry suppressed by 30-40% for the parallaxes and by a factor
+~2.5 for the proper motions. The photometry also features increased precision,
+but above all much better homogeneity across colour, magnitude, and celestial
+position. A single passband for G, GBP, and GRP is valid over the entire
+magnitude and colour range, with no systematics above the 1% level.

+### 2021 Northern Fall Interoperability Meeting Overview
+
+Janet Evans, Marco Molinaro and Patrick Dowler
+
+The Northern Fall Interop meeting was held Nov 02-04, 2021 via Zoom with 182
+registered participants from all around the globe. Interop meetings are held
+every ∼6 months and this was our fourth virtual meeting since the start of the
+global pandemic. Sessions were recorded and posted so that if you missed a
+session you can go back and view it. Here is the
+[link](https://www.canfar.net/storage/list/pdowler/ivoa/virtual2021b) if you are
+interested in session videos.
+
+The sessions were led by the IVOA Working Groups (WG) and Interest Groups (IG)
+and focused on core topics related to status and discussion of current group
+efforts. Community presentations were solicited and folded into sessions to
+provide a balance between contributed and core topics. In addition a Newcomers
+session and a session sponsored by the Committee for Science Priorities (CSP)
+rounded out the meeting. The Newcomers session was sponsored by the Education
+Interest Group and held the day before the opening of the Interop. Several
+scientific use cases were demoed using VO-standards and protocols. The aim was
+to help newcomers understand the structure of the IVOA and how Interop meetings
+are organized in order to get the most out of the upcoming meeting. We plan on
+regular Newcomers sessions at Interop meetings going forward. The CSP session
+titled “Bringing services and tools to the research community” welcomed
+presentations by projects on their IVOA support status and community
+involvement. Panelists from NASA Astronomical VO (NAVO), IPAC, Spanish VO,
+Chandra, ASVO, and ESA presented overviews of their project efforts. A
+discussion led by the CSP chair followed and focused on topics of interest and a
+vision toward the future.
+
+A new and important IVOA Architecture document (lead author Pat Dowler) was
+released just before the meeting. The document represents the current status of
+the IVOA Architecture. You can find descriptions of the IVOA Level 0, 1, and 2
+architecture, a dependency diagram showing the relationships between IVOA
+standards, a summary description of each standard, and links to each of the full
+standard documents. Here is a link if you are interested in reviewing the
+document
+
+The Closing Plenary and presentation by the TCG, emphasized progress of
+standards over the last 6 months, and reminded the audience of the Technical
+Coordination Group (TCG) and their role in the IVOA. The TCG is made up of
+Chairs and Vice-Chairs of working groups, interest groups, and committees. They
+are tasked with building consensus in the WG and community, assure coordination
+between WG/IG & the Committee for Science Priorities (CSP), liaison with the
+Executive committee, and support committee roles in the IVOA documents and
+standards process. TCG membership has a 3 year term with a possible 1 year
+extension. Members of the astronomical community are welcome to get involved in
+the IVOA and to consider a role in the TCG.

+### JVO Breaking Through the 1TB Barrier
+
+Christopher Zapart, Yuji Shirasaki, Masatoshi Ohishi, Yoshihiko Mizumoto
+
+Recently the Japanese Virtual Observatory (JVO) - part of the National
+Astronomical Observatory of Japan - has gained an important new capability.
+Using a 28 CPU-core Mac Pro workstation equipped with 1.5TB of RAM and running a
+normal production version of Rust FITSWebQL v4, they have demonstrated a smooth
+real-time preview of a 1.3TiB-large FITS file. FITSWebQL calculates in real-time
+the "-1" and "0" moments for FITS data cubes, which places extra stress on the
+server memory and CPU. In addition to the stable FITSWebQL v4, work is
+progressing on the distributed-computing FITSWEBQL v5 Supercomputer Edition,
+with the aim to offer in real-time selected higher moments too. In a quest to
+deliver the most performant system, during the development process FITSWEBQLSE
+has undergone many drastic language changes, going from Rust to C/C++, followed
+by CoArray Fortran & C, then switching over to Julia, and finally turning to
+"plain" C / FORTRAN coupled with custom distributed computing. For more details

+### VO supports the IAU protection efforts of the Dark and Quiet Sky
+
+Chenzhou Cui
+
+At a press conference on 3 February 2022, the International Astronomical Union
+announced the [selection](https://www.iau.org/news/pressreleases/detail/iau2201)
+of the SKA Observatory (SKAO) and NSF’s NOIRLab as co-hosts of the new IAU
+Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation
+Interference. The Centre coordinates collaborative multidisciplinary
+international efforts with institutions and individuals and works across
+multiple geographic areas to help mitigate the negative impact of satellite
+constellations on ground-based optical and radio astronomy observations as well
+as humanity’s enjoyment of the night sky. China-VO (National Astronomical Data
+Centre of China) and several other VO colleagues have gotten involved into the
+new center as Institutional Contributors and Individual Contributors.
+
+On 12 January 2022, Dark and Quiet Skies II for Science and Society Working
+Group [report](https://www.iau.org/news/announcements/detail/ann22002) was
+published online. The report discuss the feasibility of implementing adequate
+measures to mitigate the impact of artificial interferences. In October 2021
+more than 700 people from 76 countries took part in the United
+Nations/Spain/International Astronomical Union Conference on Dark and Quiet
+Skies for Science and Society online. The results of this meeting are contained
+in the report.
+
+Section 6.1 "Standards from the Virtual Observatory for SatHub" was contributed
+by China-VO. In the Section, VO and IVOA backgrounds are introduced briefly. VO
+standards and tools, like HiPS and WWT, and their potential contributions to
+SatHub are discussed. SatHub will act as a central virtual clearinghouse and
+repository for the coordination of effort and dissemination of data and
+information.

+### Second ESCAPE Virtual Observatory School
+
+Stefania Amodeo
+
+The [ESCAPE](https://projectescape.eu/) project held its second international
+Virtual Observatory (VO) school on February 22-24 and on March 4th 2022. As in
+the previous schools organised by the Euro-VO initiative, the goal was to
+promote and enhance the VO as framework to exploit the huge amount of data
+provided by the ever-growing number of ground-based and space facilities, as
+well as to gather requirements and feedback from the participants. VO experts
+gave hands-on tutorials on the usage of VO tools and services in “real life”
+examples of scientific applications, including the exploration of large
+catalogues like Gaia, cross-matching of big survey data, exploration of
+transient events and electromagnetic follow-up of gravitational-wave events. The
+last day was dedicated to the participants science cases and their own use of
+the VO-skills learned during the school. Planned initially as a hybrid meeting
+at the Observatoire Astronomique de Strasbourg and online, the school took place
+online exclusively due to the persistence of the pandemic situation. More
+information on the school, including the tutorial material can be found
+[here](https://indico.in2p3.fr/event/25225/).

+
+The IVOA standardised Multi Order Coverage
+([MOC](https://ivoa.net/documents/MOC/20220125/index.html)) maps offer practical
+ways to manage complex regions of the sky. In a new Astronomy and Computing
+paper, "Multi Order Coverage data structure to plan multi-messenger
+observations” [Greco et al. 2022](https://doi.org/10.1016/j.ascom.2022.100547)
+presents an application of MOC, in combination with the astroplan observation
+planning package to enable the efficient computation of sky regions and the
+visibility of these regions from a specific location on the Earth at a
+particular time. The published article includes an associated Jupyter notebook
+and a video demonstration of the workflow which provides the basis of a new
+tutorial in the [Second ESCAPE Virtual Observatory
+School](https://indico.in2p3.fr/event/25225/).

+### Multi-messenger astronomy with ESASky
+
+Deborah Baines
+
+ESASky is a science-driven discovery portal developed at the European Space
+Agency’s ESAC Science Data Centre that allows the interactive exploration of a
+large collection of astronomical data, providing a very useful tool for
+exploring the multi-wavelength sky with the click of a button. The latest
+release of ESASky is branching into multi-messenger astronomy and shows
+gravitational wave (GW) event probability maps on the sky, allowing users to
+look for electromagnetic counterparts for the GW events and using ESASky to
+quickly access all available archival electromagnetic data. Near future releases
+intend on expanding the multi-messenger feature and include, for example, the
+IceCube neutrino footprint.
+
+Additionally, the latest releases of ESASky have increased the amount of science
+ready data accessible through the tool. These include: all public CHEOPS
+observational metadata and light curves; new and updated catalogues in the high
+energy domain (such as Data Release 11 of the Fourth XMM-Newton Serendipitous
+Source catalog and the Fermi-LAT 10-year source catalog); HiPS from PanSTARRS
+and ASTRON (the TGSS ADR progressive survey and Apertif Data release 1 survey);
+the ability to include any HiPS from a URL, local computer or by browsing the
+CDS HiPS list for globally available HiPS; and the external Table Access
+Protocol (TAP) service has been expanded too, complementing the access to MAST,
+ESO and CADC data with the access to ASTRON and the HEASARC master catalogs.
+
+Finally, in collaboration with the ESA/Hubble team, ESASky now provides access
+to the Hubble outreach images on the ESA/Hubble website. Users can tour the
+Hubble outreach images overlaid on the sky, read the explanation about each
+image and link to the appropriate ESA/Hubble outreach image page.

+
+Tamara Civera
+
+The Centro de Estudios de Física del Cosmos de Aragón
+([CEFCA](https://www.cefca.es/)) is carrying out from the Observatorio
+Astrofísico de Javalambre ([OAJ](https://oajweb.cefca.es/), Teruel, Spain) two
+large area multiband photometric sky surveys, [J-PLUS](https://www.j-plus.es/),
+and [J-PAS](https://www.j-pas.org/), covering the entire optical spectrum using
+narrow and broad band filters. J-PAS and J-PLUS include coadded and individual
+frame images, dual and single catalogue data generated from coadded images, and
+photo-redshift computations.
+
+All this survey data (at the present moment, J-PLUS DR1 and DR2 and MiniJ-PAS
+PDR201912) is offered through the CEFCA Catalogues portal which provides
+advanced tools for data search, visualization and download. This powerful portal
+includes web user interface services such as sky navigator, object
+visualization, object list search, ADQL asynchronous queries interface, cone
+search and image search and download. All these services support SAMP protocol
+to interoperate and communicate with VO-compatible applications. The CEFCA
+catalogues portal also offers all this data through Virtual Observatory (VO)
+services like SIAP, SCS, TAP and catalogue and images HIPS.

+_The GALAH+ survey: Third data release_
+
+**Buder, Sven et al.**
+
+_Monthly Notices of the Royal Astronomical Society, Volume 506, Issue 1, pp.150-201_
+
+_Abstract._ The ensemble of chemical element abundance measurements for stars,
+along with precision distances and orbit properties, provides high-dimensional
+data to study the evolution of the Milky Way. With this third data release of
+the Galactic Archaeology with HERMES (GALAH) survey, we publish 678 423 spectra
+for 588 571 mostly nearby stars (81.2 per cent of stars are within <2 kpc),
+observed with the HERMES spectrograph at the Anglo-Australian Telescope. This
+release (hereafter GALAH+ DR3) includes all observations from GALAH Phase 1
+(bright, main, and faint survey, 70 per cent), K2-HERMES (17 per cent),
+TESS-HERMES (5 per cent), and a subset of ancillary observations (8 per cent)
+including the bulge and >75 stellar clusters. We derive stellar parameters Teff,
+log g, [Fe/H], vmic, vbroad, and vrad using our modified version of the spectrum
+synthesis code Spectroscopy Made Easy (SME) and 1D MARCS model atmospheres. We
+break spectroscopic degeneracies in our spectrum analysis with astrometry from
+Gaia DR2 and photometry from 2MASS. We report abundance ratios [X/Fe] for 30
+different elements (11 of which are based on non-LTE computations) covering five
+nucleosynthetic pathways. We describe validations for accuracy and precision,
+flagging of peculiar stars/measurements and recommendations for using our
+results. Our catalogue comprises 65 per cent dwarfs, 34 per cent giants, and 1
+per cent other/unclassified stars. Based on unflagged chemical composition and
+age, we find 62 per cent young low-α, 9 per cent young high-α, 27 per cent old
+high-α, and 2 per cent stars with [Fe/H] ≤ -1. Based on kinematics, 4 per cent
+are halo stars. Several Value-Added-Catalogues, including stellar ages and
+dynamics, updated after Gaia eDR3, accompany this release and allow
+chrono-chemodynamic analyses, as we showcase.

-The International Virtual Observatory Alliance (IVOA) was formed in June 2002 with a mission to facilitate the international coordination and collaboration necessary for the development and deployment of the tools, systems and organizational structures necessary to enable the international utilization of astronomical archives as an integrated and interoperating virtual observatory. The IVOA now comprises 20 VO programs from Argentina, Armenia, Australia, Brazil, Canada, Chile, China, Europe, France, Germany, Hungary, India, Italy, Japan, Russia, South Africa, Spain, Ukraine, the United Kingdom, and the United States and an inter-governmental organization (ESA). Membership is open to other national and international programs according to the IVOA Guidelines for Participation. You can read more about the IVOA and what we do at http://ivoa.net/about/.

-What is the VO?
-The Virtual Observatory (VO) aims to provide a research environment that will open up new possibilities for scientific research based on data discovery, efficient data access, and interoperability. The vision is of global astronomy archives connected via the VO to form a multiwavelength digital sky that can be searched, visualized, and analyzed in new and innovative ways. VO projects worldwide working toward this vision are already providing science capabilities with new tools and services. This newsletter, aimed at astronomers, highlights VO tools and technologies for doing astronomy research, recent papers, and upcoming events.

-### 2021 Northern Fall Interoperability Meeting Overview
-Janet Evans, Marco Molinaro and Patrick Dowler
-
-The Northern Fall Interop meeting was held Nov 02-04, 2021 via Zoom with 182 registered participants from all around the globe. Interop meetings are held every ∼6 months and this was our fourth virtual meeting since the start of the global pandemic. Sessions were recorded and posted so that if you missed a session you can go back and view it. Here is the link if you are interested in session videos.
-The sessions were led by the IVOA Working Groups (WG) and Interest Groups (IG) and focused on core topics related to status and discussion of current group efforts. Community presentations were solicited and folded into sessions to provide a balance between contributed and core topics. In addition a Newcomers session and a session sponsored by the Committee for Science Priorities (CSP) rounded out the meeting. The Newcomers session was sponsored by the Education Interest Group and held the day before the opening of the Interop. Several scientific use cases were demoed using VO-standards and protocols. The aim was to help newcomers understand the structure of the IVOA and how Interop meetings are organized in order to get the most out of the upcoming meeting. We plan on regular Newcomers sessions at Interop meetings going forward. The CSP session titled “Bringing services and tools to the research community” welcomed presentations by projects on their IVOA support status and community involvement. Panelists from NASA Astronomical VO (NAVO), IPAC, Spanish VO, Chandra, ASVO, and ESA presented overviews of their project efforts. A discussion led by the CSP chair followed and focused on topics of interest and a vision toward the future.
-
-A new and important IVOA Architecture document (lead author Pat Dowler) was released just before the meeting. The document represents the current status of the IVOA Architecture. You can find descriptions of the IVOA Level 0, 1, and 2 architecture, a dependency diagram showing the relationships between IVOA standards, a summary description of each standard, and links to each of the full standard documents. Here is a link if you are interested in reviewing the document
-
-The Closing Plenary and presentation by the TCG, emphasized progress of standards over the last 6 months, and reminded the audience of the Technical Coordination Group (TCG) and their role in the IVOA. The TCG is made up of Chairs and Vice-Chairs of working groups, interest groups, and committees. They are tasked with building consensus in the WG and community, assure coordination between WG/IG & the Committee for Science Priorities (CSP), liaison with the Executive committee, and support committee roles in the IVOA documents and standards process. TCG membership has a 3 year term with a possible 1 year extension. Members of the astronomical community are welcome to get involved in the IVOA and to consider a role in the TCG.

-### Second ESCAPE Virtual Observatory School
-Stefania Amodeo
-
-The [ESCAPE](https://projectescape.eu/) project held its second international Virtual Observatory (VO) school on February 22-24 and on March 4th 2022. As in the previous schools organised by the Euro-VO initiative, the goal was to promote and enhance the VO as framework to exploit the huge amount of data provided by the ever-growing number of ground-based and space facilities, as well as to gather requirements and feedback from the participants. VO experts gave hands-on tutorials on the usage of VO tools and services in “real life” examples of scientific applications, including the exploration of large catalogues like Gaia, cross-matching of big survey data, exploration of transient events and electromagnetic follow-up of gravitational-wave events. The last day was dedicated to the participants science cases and their own use of the VO-skills learned during the school. Planned initially as a hybrid meeting at the Observatoire Astronomique de Strasbourg and online, the school took place online exclusively due to the persistence of the pandemic situation. More information on the school, including the tutorial material can be found here.
