A RADIOOPTICAL SURVEY OF THE NORTH ECLIPTIC CAP

The Cambridge Low Frequency Synthesis Telescope has been used to surve y a region approximate to 7 x 7 deg(2) about the North Ecliptic Cap at 151 MHz with a resolution of 70 x 77 arcsec(2). The resulting radio s ource catalogue of 400 sources is complete to a peak nw density limit of 120 mJy beam(-1). Using the Cambridge APM we have searched for iden tifications on the Palomar Sky Survey plate 550 which covers much of t he survey area, and we list the 157 sources with one or more optical o bjects within 15 arcsec of the radio position.
