 * 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.
 * for each set of exposures, psphotStack generates a set of PSF-matched images, convolved to a common PSF
-* a set of radial apertures are used to measure photometry of all objects and (un-detected) matched sources.  this is done for the original convolved stacks and the PSF-matched images with full-width half-max values specified by the psphot.config key PSPHOT.STACK.TARGET.PSF.FWHM (nominally 6.0 & 8.0 pixels).

 For the radial apertures, the following annulii are used (defined by psphot.config keys @RADIAL.ANNULAR.BINS.LOWER and @RADIAL.ANNULAR.BINS.UPPER):
