7C(G) 151-MHz Northern Galactic Plane Survey Catalog

Metadata Updated: September 19, 2025

Results from a survey of the northern Galactic plane (at Declination >= 30<sup>o</sup> at 151 MHz made with the Cambridge Low Frequency Synthesis Telescope (CLFST) are presented in this table. This survey was designated the 7C(G) - i.e. the Galactic portion of the then-ongoing 7C surveys. The 7C(G) covers the regions 80<sup>o</sup> < l < 104<sup>o</sup> and 126<sup>o</sup> < l < 180<sup>o</sup>, for |b| <= 5.5<sup>o</sup>, and has some coverage to |b| ~ 9<sup>o</sup>, with a resolution of ~70 x70 cosec{delta} arcsec<sup>2</sup> (RA x Dec). The observations, data reduction and calibration of this survey are described in the reference paper, and the catalog of 6262 compact sources, with a completeness limit of ~ 0.25 Jy (250 mJy) over most of the survey region, is presented in this table. The catalog has an rms positional accuracy of better than 10 arcseconds, and the flux densities are tied to the scale of Roger, Bridle & Costain (1973, AJ, 78, 1030) with an accuracy of better than 10 per cent. This table was created by the HEASARC in October 2010 based on CDS table J/MNRAS/294/607 file 7cg.dat. This is a service provided by NASA HEASARC .
