The Molonglo Reference Catalogue of radio sources.

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 ≥ (l950) ≥ 85°.0, |b| ≥ 3°. 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^-1, corresponding to 10- 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.
