Spectra, Dimensions and Luminosities of Radio Sources in the Culgoora-3 List

The Culgoora-3 list of radio sources (Slee 1977) contains measurements at 160 MHz of about 2000 sources which had earlier been examined at 80 MHz (Slee and Higgins 1973, 1975). The observations were made with the Culgoora radioheliograph, a 3-km-diameter ring of 96 reflectors, which achieves angular resolutions (full half-power width) of 3′.7 and 1′.9 arc at 80 and 160 MHz respectively; it has an effective collecting area of ~6000 m2.
