The 7C(G) survey of radio sources at 151 MHz - the Galactic plane at 80deg <l< 104deg and 126deg <l< 180deg, for |b| <5deg.5.
Abstract
Results from a survey of the northern Galactic plane (at declination greater than about 30 deg) at 151 MHz made with the Cambridge Low Frequency Synthesis Telescope are presented. This survey is designated the 7C(G), i.e., the Galactic portion of the ongoing 7C surveys. This covers the regions l between 80 and 104 deg and l between 126 and 180 deg, for |b| less than or equal to 5.5 deg, and has some coverage to |b| of about 9 deg, with a resolution of about 70 x 70 cosec(delta) arcsec squared (RA x Dec.). The observations, data reduction, and calibration of this survey are described, and a catalogue of 6262 compact sources, with a completeness limit of about 0.25 Jy over most of the survey region, is presented. The catalogue has an rms positional accuracy of better than 10 arcsec, and the flux densities are tied to the scale of Roger, Bridle, and Costain with an accuracy of better than 10 percent.
