Scientific paper

The cluster of galaxies Abell 1314 has been observed with the Penticton synthesis telescope simultaneously at 408 MHz (73.5 cm wavelength) with a sensitivity (7 rms) near 70 mJy and at 1420 MHz (21.1 cm wavelength) with a sensitivity (5 rms) near 4.3 mJy. In addition to the 3 cluster sources detected, a further 64 background radio sources have been detected at 1420 MHz (the 20P radio survey), and 169 background sources at 408 MHz (the 21P radio survey). The surveys extend to a radius of 3.7 degrees at 408 MHz, and to 1.0 degree at 1420 MHz, from the map center at RA=11h31.5m, Dec=+49d20'. The differential source count for the background radio sources, derived at 408 MHz in the flux density range 90 mJy to 3.0 Jy, shows consistency with the Cambridge 5C5 survey at 408 MHz in a direction away from clusters of galaxies. Also, the differential count derived at 1420 MHz in the flux density range 10 mJy to 330 mJy is consistent with the Westerbork LBDS survey at a nearby frequency away from clusters of galaxies. We find no candidate for very steep spectrum "relic" sources in this cluster of galaxies, nor for very flat spectrum "blue" background radio galaxies behind the cluster. (5 data files).
