... The procedure involves fitting the point-spread function to one or more sources by a least-squares fit. The background can either be determined in the fit, or a fixed background value. ... For more details of the PSF fitting method please refer to the documentation on the SAS task omphotom . The weighting scheme used in the fitting can be either 1/pixel variance or 1 (equal weights). For information about how the latter is done, please refer to the documentation for the SAS task omphotom . ...
