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.
