Abstract:
Detailed identification of radio sources within the Abell radii
in 26 rich galactic clusters of the FIRST catalog with optical
objects of the APM and DSS surveys had been carried out. Of the
326 radio sources in the cluster fields, 99 are identified, 40
have probable identifications, and 187 are unidentified. Among
last sources, 20 are definitely located in the clusters and
34 are cluster members with high probability. Thus, 30-40% of the
FIRST radio sources could be identified using APM and DSS data,
and there were two sources in each cluster on the average.
