Description


The 7C survey of radio sources is being made with the Cambridge Low-Frequency Synthesis Telescope at 151MHz, with an angular resolution of 70x70cosec{delta}.arcsec^2^. We present the results from one part of of this survey covering 0.144sr in two areas of sky centred at RA=10h28min, DE=41{deg} and RA=06h28min, DE=45{deg} and reaching a limiting flux density of 50mJy. A list of the positions, flux densities and angular sizes of 4723 sources is presented; the position errors are in the range 1-3arcsec for sources with flux densities greater than 500mJy, and the flux density errors are typically 18mJy. About 10 per cent of the sources have apparent angular sizes greater than 60arcsec. The derived source counts are as accurate as those presently available at 405 and 1400MHz and show similar behaviour; in particular the convergence slopes are the same. The median spectral index between 151 and 408MHz remains constant at ~0.9 between 10 and 0.5Jy at 151MHz.
