      Description

      HSC internal release processing uncovered a bug in our peak culling in MergeCoaddDetectionsTask, due to a schema string with periods instead of underscores. The result is that when testing how many bands a source appears to have been detected in, the result is always zero.

      This has apparently been present on the LSST for a long time (possibly since the code was ported there), and has gone unnoticed because this test is only operative in the very largest blends, which are moderately rare in the Wide survey. We certainly should have spotted it in the UltraDeep RC tests, however; we need to make sure our RC tests include checking for changes in the number or density of detected sources.
