A Catalogue of Small-diameter Radio Sources Close to the Galactic Plane

Abstract

A catalogue of 'smaIl-diameter' galactic radio sources observed at a frequency of 408 MHz with the Molonglo radiotelescope is presented. The catalogue covers an area of 0·40 sr enclosed in the range [II = 190°-360°-50°, 1 bIll..;; 3°. The sources listed are those which show no significant broadening of the ~ 3' arc aerial beam. Small-diameter features bounded or confused by extended regions of emission are not included. A total of 513 sources are listed above a flux density of O' 6 Jy. While most of these are expected to be extragalactic, the list includes some known pulsars and small-diameter HII regions. The catalogue should form a useful search list for the identification of other such galactic objects.
