            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.  It  contains  information  from  all  major
            astronomical  journals  and  catalogs  and is also useful in
            providing a complete cross-reference of identifications  for
            an  object or for searches of known objects around a coordi-
            nate position.  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.

            and dial-in access may be offered in the future, as  person-
            nel  time  becomes available.  (This is an interactive data-
            base.)
