Faint Object Classification and Analysis System (FOCAS)
FOCAS 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. FOCAS may be used on any type of
astronomical image but it was primarily designed for the optimal
detection of small faint objects and their classification as stars,
galaxies, or noise. It is largely automated for the measurement of
large numbers of objects for various statistical studies and so the
photometry, astrometry, and classification are of moderate accuracy.
FOCAS is not intended for very crowded stellar fields where point
spread function fitting methods are more appropriate, or for large
bright objects where surface brightness methods apply.
Version March, 1998
