Description:
    The Molonglo Reference Catalog of Radio Sources results from a 408-MHz
    survey observations made with the Molonglo Radio Telescope (Australia)
    between 1968 and 1978. The survey covers 7.85sr of the sky between the
    declinations -85° and +18°, excluding the strip of the
    galactic plane (|b|≤3°). The nominal beamwidth is 2.62arcmin
    in right ascension and 2.86sec(δ+35.5)arcmin in declination.
    There are 7347 sources with flux density S≥1Jy, at which level the
    catalogue is substantially complete.

    A new version of the catalog has been done in 1990 (Cat. VIII/16).

Note (1): An asterisk indicates that the measurements obtained from two
     or more independent transits were scattered more than expected.
Note (2): a combination of the following:
      P = (or blank) point source
      A = slight extension
      E = extended
      C = complex
      M = catalogued neighbour
      N = uncatalogued neighbour
Note (3): Cross-references exist with the following catalogs:
      P = Parkes catalogues (see Cat. VIII/15)

History:
  * 12-May-1981: The catalog on 9-track magnetic tape was kindly
       prepared by M.I. Large (Sydney Univ.) to C. Jaschek (CDS)
  * 29-May-1991: Catalog renamed from VII/29 to VIII/2
