 With fix-A applied -- 
  * large scatter removed (see scatter in original plot at beginning of section)
- * appears to be a clear mean offset of ~0.07 mag (diffim PSF_MAG brighter) Is this similar to other convolution mag offsets? Also not all unlikely that a few could be as high as ~0.15 mag offset as seen in the MD10 example above

Also not all unlikely that a few could be as high as ~0.15 mag offset as seen in the MD10 example above. It is also important to note also that the photerr on the diffim photometry is typically of order 0.1-0.15 for this sample as well when using the default convolved refstack.
  * also appears AP_MAG may have two groupings, splitting earlier and later data moves contribution mostly randomly (time split can involve data quality and skycell position since mover)
