Description:
"408-MHz survey observations made with the Molonglo Radio Telescope
have been used to prepare a catalogue of 12 141 discrete sources of
listed flux density >= 0.7 Jy. The survey covers 7.85 sr of the sky
defined by +18.5 (deg) >= dec(1950) >= -85.0 (deg), mod(b) >= 3 (deg).
A few sources beyond the declination limits are also included. The
catalogue comprises celestial coordinates with standard error
typically lying between 3 and 10 arcsec and 408-MHz flux densities
with standard error typically lying between 4 and 10 per cent.
Galactic coordinates, notes on source morphology and cross-references
to the Parkes Catalogues are included. The overall source density is
1500/sr, corresponding to 0.001 per beam area. There are 7347 sources
of listed flux density >= 1.00 Jy, at which level the catalogue is
substantially complete. The reliability is believed to be better than
99.9 per cent." The MRC was re-issued in 1990 with the original B1950
coordinates supplemented by J2000 values, and an additional
cross-reference flag `J' added to denote (extended) sources imaged at
843-MHz by P.A. Jones. No other alterations were made to the original
release. The MRC is now available on 5.25 inch, 1.2 Mbyte MS-DOS (IBM)
floppy disk (0.5 inch magnetic tape is also available, but is not the
preferred medium). In the floppy disk format, simple software is
provided to facilitate use of the catalogue on a PC computer.
