Scientific paper

The deconvolution effect on point sources has been investigated empirically, and the results of experiments with low- and high-signal-to-noise-ratio Faint Object Camera (FOC) images of point sources in crowded and uncrowded fields are presented. The approach was to create careful simulations of real FOC images, deconvolve them, and compare the resulting magnitudes with their original values. The similarity between the results obtained using deconvolved data and simple aperture photometry on the original undeconvolved data demonstrates that there is not much to gain by deconvolving FOC images of point sources to do photometry.
