Identification of Two Southern Quasi-stellar Objects

Abstract

A number of possible quasi-stellar objects have been found from a search of the Palomar Sky Survey plates for identification of radio sources in the Parkes catalogue (Bolton, Clarke, and Ekers 1965). Confirmation of the identification of two of these sources, 1327-21 and 2115-30, has now been obtained from both precise position measurements and photoelectric observations. As quasi-stellar objects generally are of very small radio diameter, the optical positions can be used as primary calibration points for southern radio telescopes.
