+
+Discovered for many inputs into ppStack (i.e., deep and even refstacks), that the PSF in the output convolved stack grows with the number of inputs beyond the initial target PSF.
+Had been missed due to convolved stacks really only being used for magic, but was noticed with some M31 analysis and deepstacks of MD04.
+
+Other issues:
+ * hard limit on number of inputs (solved: descrip to watch for)
+ * heavy RAM use
+ * change the target PSF FWHM selected 
+
+Branch for testing (currently r32161 from last summer -- '''need to update..''')  -- http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/browser/branches/meh_branches/ppstack_test
+ * many outputs turned on (runs slower, makes many many files)
+ * ppStackMatch.c -- need add a TESTING2 for reading in already processed conv images..
+ * ppSubMatchPSFs.c has TESTING but not ifdef at start, is a .DEBUG. used to trigger?
+
+= Test Sets =
+More easily setup than for testing ppSub, need a large number of a variety of inputs and some number of similar inputs.
+
+== MD04 ==
+
+Sample of 20 and 100 drawn from the the [MD04.V3deepstack | MD04.V3 GR0 deepstack] set.  
+ * FWHM in stack logs.. add how compare to psphot? ''' need to add histogram of both actual inputs'''

+Batch scripts for running in /data/ipp059.0/mhuber/testppstack_deep201111/MDdeeptest
+
+
+== Sim ==
+A small variety set of many groups for 20 and 100 inputs. Also sample of two similar inputs (TBA).

+= Tests = 
+
+ * do clean simulated images suffer the same problem? Can then use for more detailed testing since faster to run than MD04 skycell and not particular to GPC1 data.
+ * how is it related to the range of inputs and number
+ * what are the output convolved images being stacked, what is the target the images are being convolved to
+ * need to understand what the code does, so first test is to look at each output, add others and step through the code...
