Abstract

We have measured the 2.3 GHz total and correlated flux densities on a baseline of 275 km of all sources in the Parkes catalogue which

  1. (i) are south of declination +10°,

  2. (ii) have a catalogued 2.7 GHz total flux density exceeding 0.5 Jy, and

  3. (iii) have a 2.7/5.0 GHz spectral index flatter than −0.5.

More than 14% of the sample showed visibility amplitudes greater than 0.9, and more than 72% showed visibility amplitudes greater than 0.5. Of the sources with optical or other identifications 79% were quasars. In this paper we briefly summarise the results of this survey.
