Source-Finding Documentation

The source-finding and analysis package supports analysis of processed radio synthesis observations, including source detection and extraction, profile fitting, and writing to the database. This package is a reimplementation of the source-finding algorithms of Duchamp, with an emphasis on the processing of ASKAP-scale data sets, and providing the functionality required by the Survey Science Projects.
