Abstract
We propose a two-dimensional galaxy fitting algorithm to extract parameters of the bulge, disk, and a central point source from broadband images of ga laxies. We use a set of realistic galaxy parameters to construct a large nu mber of model galaxy images, which we then use as input to our galaxy decom position program to test it. We elucidate our procedure by extracting param eters for three disk galaxies-NGC 5326, 5587, and 7311-and compare our resu lts with those previously reported in the literature.
