Abstract:
Stellar photometry of simulated HST uncorrected and corrected images of
a crowded star cluster has been carried out before and after deconvolution
(with RMG, R-L, MEM, etc.) to optimize the reduction procedures
and compare the degree of completeness and photometric accuracy actually
achievable in the various cases. Experiments are also presented on the
description of the surface brightness profiles of simulated clusters
with different deconvolution techniques and sizes of the adopted PSF and
data matrices.
