... The task first computes a background image in order to identify pixels that may be part of a source. The task uses two different algorithms for detecting ``point'' and ``extended'' sources. ... If a likely source is found its position and shape parameters are computed by moments and the pixels assigned to the source are set equal to the source number. ... The source is again classified as either ``point'' or ``extended'' from a comparison of its with to that of the PSF width. ...
