      Description

      We have an algorithm on the HSC fork that modifies AssembleCoaddTask to clip outliers in a much safer way, based on detecting contiguous regions in the difference between a non-clipped coadd and an aggressively-clipped coadd, and only rejecting pixels that are outliers in a single epoch.

      One complication for this code transfer is that some of the coadd code has been refactored on the HSC side, and there may be code in hscPipe that duplicates much of what's in pipe_tasks. We may need help from Paul Price to resolve those inconsistencies before tackling this issue.

      Once that's done, HSC code can be transferred from the following issues:
