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
