Lunar occultation observations of 25 radio sources made with the Ooty radio telescope. List I

Abstract

A survey of radio sources by the method of lunar occultation is being carried out at Ootacamund in India with a large steerable radio telescope whose collecting area is 8700 m². Results for 25 weak radio sources with flux densities lying in the range 0.4 to 4 fu at 327 MHz are presented here. Seven sources have clear double components with separations ranging from 2.5 to 20 arc sec. Optical identifications have been suggested for 8 of the 25 sources, 5 of which are possibly QSOs. The unidentified radio sources seem to be galaxies with high redshifts.
