Abstract
We present detailed radio and optical parameters for the stronger radi o sources iri 58 Abell cluster fields observed with the Very Large Arr ay (VLA) using scaled arrays at 1.5 and 4.9 GHz. These sources compris e a complete sample with 1.5 GHz flux density greater-than-or-equal-to 20 mJy and cover a combined sky area of 3.5 x 10(-5) sr. The cluster fields were distributed over 24 h of RA and between declinations +35-d egrees and -30-degrees. Contour maps at two frequencies are presented and source parameters such as position, angular size, spectral index, linear polarisation and core flux density are tabulated. We also deriv e the emitted power and linear size for those sources close to the clu ster centres and therefore highly likely to be cluster members. We att empt to identify all these radio sources with optical images on the Pa lomar and SERC survey plates and give their accurate optical coordinat es, morphologies and apparent magnitudes.
