Ooty Occultations of 76 radio sources

Abstract

Positional and structural information derived from lunar occultations observed at 327 MHz is presented for 76 radio sources, most of them of flux density less than 2×10 -26 Wm -2 Hz -1 . Only 16 sources are optically identified. Two of the stronger sources in the list, viz. PKS 1417-19 and MSH 16-205 have a head-tail type of radio structure. PKS 1417-19 appears to be associated with a small chain of faint galaxies. It is interesting that a close group of five radio sources, each with flux density ≥0.5 f.u. appears to be physically associated with the cluster Zw 0210.1 + 1857. One of the five sources coincides with a 19-mag BSO, while none of the other four is identified with an optical object on the basis of positional agreement.
