A VLA-ASTERISK SURVEY OF RICH CLUSTERS OF GALAXIES .3. THE WEAKER SOURCES - MAPS AND IDENTIFICATIONS

We present radio and optical parameters for 737 weak sources in 60 Abe ll cluster fields observed with the Very Large Array (VLA) using scale d arrays at 1.5 and 4.9 GHz. The measurements extend to a lower 1.5 GH z limit of 1.0 mJy and comprise a complete sample with 1.5 GHz flux de nsity 2.5 less than or equal to S-1.5 < 20 mJy. The combined sky area within the half-power circle on the maps is 3.5 x 10(-3) sr, and the c luster fields are distributed over 24 h of right ascension and between declinations +35 degrees and -30 degrees. Contour maps of the extende d sources at 1.5 GHz are presented and source parameters such as posit ion, angular size and spectral index are tabulated. We also derive the emitted power and linear size for those sources with published redshi fts. We try to identify the radio sources with optical images on the P alomar and SERC survey plates and give their accurate optical position s, morphologies and apparent magnitudes.
