+Histograms of the FWHM major and minor from camera stage for reprocessed g-band exposures (red) and refstack.20110722 (top blue), psfrefstack.20110814 (middle blue) and refstack.20100721 V2 (bottom blue). The unmatched blue/red overlap for refstack.20110722 FWHM major<6.5 pixels for exposures in the refstack is from using also low zeropoint and bright background cuts. Psfrefstack used <5.1 pixels.

 Summary comparison table with the approximate FWHM (major) as the PSF FWHM from a center field skycell (V3=055, V2=078) after running psphot on the stacks.

+Troubled skycells: none in initial inspection. Far outer edges with few dithers may/may not have successful skycells. Sample skycell coverage map by good_frac with N input warps, N rejected warps, dtime_script for making stack, and flag any quality error that rejects an entire skycell (ERR). The ~110-125 input warps provided a sample for some of the far outer skycells from earlier dithers to be covered still.
