I completed the attempts to run all of the imageDifference and coadd measurements, at least to the point where I don't believe that problems are the result of datasets.
For SDSS, I have been able to run both imageDifference and the coadd measurements all the way through using the new datasets added in this ticket. Coadd measurements using multiBand.py were not without problems. There were problems with the "CLIPPED" pixel in PixelFlags.cc, propagateVisitFlags does not seem to work correctly, However, I was able to get through detectCoaddSources, mergeCoaddDetections, and measureCoaddSources with the problems disabled with config settings.
For Decam, I was not able to get through measureCoaddSources because the data I was using had a filter="VR" which did not work with meas_astrom. Things looked good with decam otherwise.
For HSC, I am still waiting for CI_HSC to demonstrate that coadd assemble and coadd measurement is still working. Since difference imaging was not working with HSC prior to this ticket, I have not tested it.
UPSHOT: I think that the datasets are working with SDSS, HSC, and DECAM, even though different bits of difference and coadd are failing in places.
