				<para>
    This SAO catalogue (Smithsonian Astrophysical Observatory Catalogue of
    258,997 stars, 1966; see catalog &lt;I/131>), connected to the CSI
    (Catalogue of Stellar Identifications, see Ochsenbein et al. 1981),
    enables researchers to retrieve reliable astrophysical data for about
    20,000 stars. This includes SAO identifications, CSI identifications,
    equatorial coordinates (B1950), Galactic coordinates, proper motions,
    photometric data, spectral classifications, radial velocity, etc. The
    SAO/HD cross index for about 188,000 stars allows users to find (or
    enter) the catalog with the HD number of the star. The notes
    contain detected errors, the value of the trigonometric parallax taken
    from the Jenkins' (1952, 1963) catalogues, the double star designation
    ADS or IDS, and the name of the star.</para></description>
