      Description

      We encountered a few processing failures in the HSC S19A production around the edges of the field:

      RuntimeError: AST: Error at line 53 in file src/FitsChan.cc.astFindFits(FitsChan): Cannot encode floating point value nan into a FITS header card for keyword 'BGMEAN'.
      

      The problem occurs in deblendCoaddSources, and brings multibandDriver down.

      The coadd image (tract=9812 patch=5,3 filter=NB0921) is completely NAN. In this case, the only contribution to the image is visit=67792 ccd=103.

      Make this fail nicely.
