cds-question@unistra.frradio-continuum-emissionradio-sourcessurveysPart 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 132{deg}^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.2008AstBu..63..346Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/VIII/86CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVIII/33 : RATAN (RC) Catalog spectral characteristics (Bursov+ 1989)VIII/40 : GB6 catalog of radio sources (Gregory+ 1996)VIII/42 : Texas Survey of radio sources at 365MHz (TXS) (Douglas+ 1996)VIII/65 : 1.4GHz NRAO VLA Sky Survey (NVSS) (Condon+ 1998)VIII/71 : FIRST Survey Catalog (FIRST) (Becker+ 2003)VIII/79 : VLA Low-frequency Sky Survey at 74MHz (VLSS) (Cohen+ 2007)II/282 : SDSS Photometric Catalog Release 6 (Adelman-McCarthy+ 2007)J/A+AS/87/1 : RATAN-600 7.6cm catalog of radio sources (Parijskij+ 1991)J/AZh/72/613 : Optical identification of radio sources (Kopylov+, 1995)J/AZh/73/835 : Identifications of objects from RC Catalog (Fletcher+ 1996)J/other/BSAO/40.5 : RATAN-600 RC radio sources (Parijskij+ 1996)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=VIII/86https://vizier.iucaa.in/viz-bin/VizieR-2?-source=VIII/86http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=VIII/86https://vizier.cds.unistra.fr/viz-bin/votable?-source=VIII/86https://vizier.iucaa.in/viz-bin/votable?-source=VIII/86http://vizieridia.saao.ac.za/viz-bin/votable?-source=VIII/86GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table VIII/86/RCsample (Analysis of the RC catalog sample in the region overlapping with FIRST and SDSS)https://vizier.cds.unistra.fr/viz-bin/conesearch/VIII/86/RCsample?https://vizier.iucaa.in/viz-bin/conesearch/VIII/86/RCsample?http://vizieridia.saao.ac.za/viz-bin/conesearch/VIII/86/RCsample?GETtext/xml+votable180.050000true122.909829174.848663890.0055555555555555565/2057 6597 6921 6/4116 4117 4118 4121 4122 4123 4133 4134 4137 4138 4160 4224 8213 8214 8215 8217 8218 8220 8233 8234 8235 8240 8256 8320 21887 21972 21973 21974 21977 21978 21979 21980 21989 22000 26069 26070 26073 26074 26075 26085 26086 26090 26091 26096 26325 26326 26329 26330 26331 26332 26340 26342 26344 26345 26346 26393 26394 26395 26403 26405 26406 26407 26409 26410 26416 27093 27094 27095 27097 27098 27100 27109 27110 27113 27114 27115 27116 27349 27350 27353 27354 27355 27365 27366 27367 27369 27370 27371 27372 27376 27413 27414 27417 27418 27419 27420 27429 27430 27433 27434 27435 27436 27456 27520 27669 27670 27671 27673 27674 27675 27689 27690 27692 27712 31359 31423 31445 31446 31449 31450 31451 31452 31461 31462 31465 31466 31467 31468 31472 31525 31526 31527 31529 31530 315324.903291545219051e-26 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/VIII/86?format=asciiRadiodefaultVIII/86/RCsampleAnalysis of the RC catalog sample in the region overlapping with FIRST and SDSSMTMorphological type (4)src.morph.typecharTypeSSDSS object typesrc.class.starGalaxycharrecnoRecord number assigned by the VizieR team.
