Analysis of a Sample of RC Catalog Objects in the Region Overlapping with the Areas Covered by FIRST and SDSS Surveys. II: Optical Identification with the SDSS Survey and USNO-B1 and 2MASS Catalogs

Abstract

We report the results of optical identification of a sample of RC catalog radio sources with the FIRST and SDSS surveys. For 320 sources identified with NVSS and FIRST objects we perform optical identification with the SDSS survey. When selecting optical candidates we make maximum use of the information about the structure of radio sources as provided by the FIRST survey images. We find optical candidates for about 80% of all radio sources.
