-These have been chosen to match the apertures defined by SDSS (see [http://www.sdss.org/dr7/algorithms/photometry.html#photo_profile photo profile]).  For any given `psphotStack` analysis, the radial apertures actually used are written to the header of the corresponding XRAD extension (see keywords RMIN_NN and RMAX_NN).

+NOTE: The psphotStack annulus numbers are zero-offset arrary indices. PSPS uses unity offset. The corresponding PSPS radial apertures are shown in the table above.
 
 Note: `psphotStack` calculates the total flux within each circular aperture (not the annulus).  The following values are saved in the smf/cmf file in the `XRAD` extension:
