Incorrect photometry when merging child objects
Issue raised Sep 13 2017, 12:45 AEST; last modified Sep 13 2017, 12:45 AEST
The algorithm used to merge close detections into a single object has been discovered to incorrectly combine the photometry, resulting in an overestimate of the source brightness in the master catalogue by up to a factor of 2 (0.75 mag).
We recommend excluding sources with [filter]_nch (or nch_max) > 1 from your table queries.
