The Faint Object Classification and Analysis System, called FOCAS, is a set of programs for creating and manipulating catalogs of objects from digital astronomical images. The creation of a catalog is accomplished by an automatic threshold detector where the threshold is measured relative to a simultaneously determined background. The manipulation of catalogs includes the separation of merged objects, the measurement of various position, shape, and photometric parameters, the astronomical classification of the objects, and the display and analysis of the catalogs. This paper describes much of the workings of FOCAS with reference to the FOCAS User's Manual.
