-Other issues:
+Other issues: (will add to as things are found/discussed)
  * hard limit on number of inputs (was shell descriptors limit of 1024 easily being reached with image,mask,weight,psf,cmf files for each input. Raised to 65535 now by default.)
  * selection of target PSF FWHM, worse input PSF not necessarily best choice as could end up being rejected and only a few inputs may be that large (not representative)
  * heavy RAM use (10-20GB typical for 100+ inputs) -- tests run unoptimized, will need to look at effect 
  * long run-time for 20+ inputs, 400 inputs order 12-14hr (use method similar to psphotStack?) -- tests run unoptimized, will need to look at effect
-
+ * seeing more of the fault 5 stack events for MD nightly where inputs have strangely small <2 pixel input PSF. BIll has quality setting but not turned on, more of an issue possibly with the PSF determination for edge skycells with possible poor extrapolation from center of the field. not really a ppStack issue but..

-How is the Target seeing FWHM selected to be >7.5 when limited to that on the input images. Are input images not being rejected?  Somewhat part of next section on Target PSF, but need to trace out here. Split up 400 set into subgroups and ran, looks like is not using the rejected but is growing itself in converting to the PSF.MODEL PS_MODEL_PS1_V1?

  * would be helpful to have other stats, at least min/max inputs
- * s055g - in smaller sub-sets ~100, target is ~9.45 and similar output. limiting input FWHM <7.1 selects a  target ~8.4. rejection for >7.5 is active.

  * s055r - '''TODO'''
