Bright extragalactic radio sources at 2.7 GHz- III. The all-sky catalogue.

The authors catalogue the brightest extragalactic radio sources at 2.7 GHz. The complete sample comprises 233 sources found in the major centimetre-wavelength surveys carried out at ANRAO/Parkes, NRAO/Greenbank, and MPIfR/Bonn; the sample covers 9.81 sr and has limits S_2.7 = 2.0 Jy and |b| > 10°. A critical re-analysis of the data shows that 227 (97 per cent) have optical identifications and 171 (73 per cent) have measured redshifts. The implications of the catalogue statistics for the luminosity functions of different radio-source populations are considered.
