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.

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.
