 ## Version 0.5.1
 
 - Bugfix: RecSec subset streams, which checked that 'st' and 'st_syn' had the same stations, would not run for streams of the same length, leading to edge case where same length streams would plot out of order because they had not been sorted. removed the criteria and now subset streams runs at all times
