            SIMBAD is a complete database  for  observational  data  and
            bibliographic references accessible by the name or number of
            the astronomical object.  It is nearly complete to 1950  for
            stars and to 1983 for non-stellar objects. It excludes solar
            system objects. SAO is the official NASA agent in  the  U.S.
            for  this  resource. The database is maintained in France by
            the Centre de Donnees astronomique de Strasbourg (CDS).  SAO
            provides administrative, network, and user assistance in the
            U.S.

            offered in the future, as personnel time becomes  available.
