Beginning of ReadMe : VIII/86 Analysis of the RC catalog sample. (Zhelenkova+ 2008-2009) ================================================================================ Analysis of the RC catalog sample in the region overlapping with the regions of the FIRST and SDSS surveys: I. Identification of sources with the VLSS, TXS, NVSS, FIRST, and GB6 catalogs. II. Optical identification with the SDSS survey and USNO-B1 and 2MASS catalogs. Zhelenkova O.P., Kopylov A.I. <Astrophys. Bull. 63, 346 (2008); 64, 109 (2009)> =2008AstBu..63..346Z =2009AstBu..64..109Z ================================================================================ ADC_Keywords: Radio continuum ; Radio sources ; Surveys Keywords: radio continuum: general - surveys - radio sources: general - radio sources: identifications Description: Part 1 contains parameters in 74-4850MHz frequency range for 320 radio sources of the RC catalog. After visual inspection of the sample on images of the NVSS and FIRST surveys we defined morphological type, number of FIRST counterparts of each source and angular size for multi-components sources, also refined coordinates of the RC catalog sources. We used GB6 images for flux density estimations of weak sources of our sample. Two-frequency spectral indices are also presented. Part 2 contains results of optical identification of the 320 radio sources of the RC catalog with the SDSS survey. We visually identified FIRST and SDSS data based on refined coordinates and morphological types of the RC catalog sample from paper 1 (part1). We searched the literature, NED and SDSS databases to find data about type of optical candidates, their spectral redshifts, partially photometric redshifts, estimated likelihood ratio and likelihood ratio cut-off for the objects. Abstract of paper I: 432 radio sources of the RC catalog produced in 1980-1985 at RATAN-600 radio telescope based on a deep survey of a sky strip centered on the declination of the SS433 source are identified in the region overlapping with FIRST and SDSS surveys (about 132deg^2^ large). The NVSS catalog was used as the reference catalog for refining the coordinates of the radio sources. The morphology is found for about 75% of the objects of the sample and the ratio of single, double and multicomponent radio sources is computed based on FIRST radio maps. The 74, 365, 1400, and 4850MHz data of the VLSS, TXS, NVSS, FIRST, and GB6 catalogs are used to analyze the shape of the spectra. Abstract of paper II: 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 70% of all radio sources.
