Analysis of the RC Catalog Sample in the Region Overlapping with theRegions of the FIRST and SDSS Surveys: I. Identification of Sources withthe VLSS, TXS, NVSS, FIRST, and GB6 Catalogs

摘要

Radio sources of the RC catalog produced in 1980-1985 at RATAN-600 radio telescope basedon a deep survey of a sky strip centered on the declination of the S S433 source are optically identifiedin the region overlapping with FIRST and SDSS surveys (about 132 □ large). The NVSS catalog wasused as the reference catalog for refining the coordinates of the radio sources. The morphology is found forabout 75% of the objects of the sample and the ratio of single, double and multicomponent radio sources iscomputed based on FIRST radio maps. The 74, 365, 1400, and 4850 MHz data of the VLSS, TXS, NVSS,FIRST, and GB6 catalogs are used to analyze the shape of the spectra.
