      Description

      A common failure mode in measureCoaddSources.py is:

      \[...\]
        File "/global/common/cori/contrib/lsst/lsstDM/v13_0/Linux64/meas_deblender/13.0/python/lsst/meas/deblender/plugins.py", line 819, in _handle_flux_at_edge
          psfim = psf.computeImage(afwGeom.Point2D(xc, yc))
        File "/global/common/cori/contrib/lsst/lsstDM/v13_0/Linux64/afw/13.0/python/lsst/afw/detection/detectionLib.py", line 3767, in computeImage
          return _detectionLib.Psf_computeImage(self, *args)
      lsst.pex.exceptions.wrappers.RangeError: 
        File "src/WarpedPsf.cc", line 74, in lsst::afw::geom::Box2I lsst::meas::algorithms::{anonymous}::computeBBoxFromTransform(lsst::afw::geom::Box2I, const lsst::afw::geom::AffineTransform&)
          Unexpectedly large transform passed to WarpedPsf {0}
      lsst::pex::exceptions::RangeError: 'Unexpectedly large transform passed to WarpedPsf'
      

      This usually signals bad astrometry in one of the inputs, but which input? It would be helpful if CoaddPsf could identify the input image in question.
