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.

-In tracking down an odd skycell (048, y-band) highlighted an odd rejection case and prompted a modification to the criteria based on the RMS (see r32170). This may help reduce large number of rejections in future refstacks but likely needs some tuning (currently still rejecting too many?). Using the PSF FWHM cuts in the DEEP_STACK reduction also helps reject strange input warps as well.

+Sample skycell coverage map by good_frac with N input warps, N rejected warps, dtime_script for making stack, and if quality error that rejects entire skycell. The ~130 input warps provided enough of a sample for the outer edge skycells from earlier exposures.

 Initially the stack processing was run without a reduction type and thus with just defaults that compresses the images (version 20110722gri, 20110715y, 20110718z) along with a test sample to produce the best PSF focused set (MD10.psfrefstack.20110814) and a test best deep stack (just skycell.055, i-band, not distributed). This is not optimal and a re-run was done with the DEEP_STACK reduction type (version 20110821) and should be the one used. The different reduction types include:
