Two-dimensional galaxy image decomposition

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