      Description

      The PSF calculated for DcrCoadds in DM-19517 fails in some cases for Decam data. The source detection task that was used incorrectly scales the source detection threshold, and can result in no sources being detected. The detection Task should be switched to the base version, and it should possibly only be a warning if psf measurement fails, rather than an error.

            This is related to our brownbag discussions of source detection. Here, I was using the wrong version of the task, and needed to set some different config options for it to run reliably.

            Looks good, with very minor comments on GitHub. I'm glad our source detection brownbag series helped you realize you should be using a different task for this!
