+`psphotStack` is the program used to perform object detection, classification, and photometry analysis for the stack images.  The treatment of stacks is slightly different from the treatment of individual exposures in a few respects:
 
- * a set of skycell images is processed at once in {{{psphotStack}}}, nominally all five filters `grizy`.
+ * a set of skycell images is processed at once in `psphotStack`, nominally all five filters ''grizy''.
  * both raw (unconvolved) and convolved stacks are loaded.  the raw stack is used for detection, while the convolved stack is used for photometric and morphological analysis.  '''update''': as of r33964, we are using the 'raw' images for both detection and morphological analysis (but not radial apertures, discussed below).
  * objects detected in the input frames are joined across the multiple filters to define common objects.  Any object for which a sources is NOT detected in any of the frames is used to define a source on those frames (MATCHED sources).  PSF photometry is performed on the matched sources.
