 past/current ppStack.config for STACK_THREEPI:
  * PSF.INPUT.MAX  12.0 -- anything >12 pixels excluded (3")
-* PSF.INPUT.CLIP.NSIGMA  NAN -- not used, but would redefine the INPUT.MAX to be clipped_mean + NSIGMA*clipped_stdev
+ * PSF.INPUT.CLIP.NSIGMA  NAN -- not used, but would redefine the INPUT.MAX to be clipped_mean + NSIGMA*clipped_stdev
 
 proposed:
-* PSF.INPUT.MAX 8.0 (or 2", MD deep stack is set for 7.5)
-* PSF.INPUT.CLIP.NSIGMA 2.0 (or 1.0?)
+ * PSF.INPUT.MAX 8.0 (or 2", MD deep stack is set for 7.5)
+ * PSF.INPUT.CLIP.NSIGMA 2.0 (or 1.0?)
 
 Chris quickly looked at the FWHM of the exposures going into LAP stacks and order 90 percentile are <8 pixels. The NSIGMA is more difficult to quantify, so the general question is do we want to just help trim off more of the poorest inputs to keep the convolved target PSF more regular or be much more restrictive to improve the convolved target PSF at the cost of the number of inputs (maybe 10-30% at times for NSIGMA of 1). Any additional exclusion cuts include images that go into making the unconvolved stack as well.
