I have below the comparison between the images after 1GC, after 2GC(selfcal with quartical) and the last one after 3GC(peeling with quartical).
The same can be found in these directories respectively:
/net/garfunkel/home/samboco/Image-boom/obsuhf1/im1/im1-MFS-image.fits
/net/garfunkel/home/samboco/Image-boom/obsuhf2/im4/im4-MFS-image.fits and
/net/garfunkel/home/samboco/Image-boom/obsuhf/im5/im4-MFS-image.fits

Screenshot from 2022-09-26 10-57-33

as we can see, peeling is showing some improvement when compared to imaging after selfcalibration. Most of the artifacts are not present in the image after Peeling, but we still have a significant amount of artifacts in the image.
