+ * ppStack testing 
+  * using SYS.ERR=0 for stacks to avoid injecting a largely scaled model flux profile into the variance/weights results in ~no PSF growth for simulated images, <10% with 20 MD04 inputs (5.3->5.8), ~10% for 100 inputs (6.9->7.8) and ~40% for 400 inputs (7.1->9.8). Started looking into the driving factors in the very large N input case.
+  * started looking into the setting of the target PSF for the convolved stacks and for not using roughly the largest PSF from the input images.

  * Spent the week debugging psphotStack problems and building tools to help that effort.
