Description The Rejected source catalogue includes positions, proper motions and mean photometry of ~560 square degrees of the southern Galactic disc and bulge in Z, Y, J, H, Ks bands, using data from Jan. 2010 to Sep 2019. Here are the sources classified as duplicates, erroneous detections, etc., but there could be also interesting sources like photometric transients.
Please refer to the full data release description for further information.
