 As before, the FWHM_MAJOR with the central skycell can be variable and more so with largely different input sets. Comparison with the psf_major/minor maps are more useful between refstack versions.

  * as with all past refstacks, generally edge skycells have issues -- need better containment of those still. (see core coverage below).
