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).

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
