About the paperAbstract
We present early results of multiband study of the RATAN Cold Revised (RCR) catalogue obtained from seven cycles of the "Cold" survey carried out on the radio telescope RATAN-600 at 7.6 cm in 1980-1999 at the declination of the SS433 source. We used the 2MASS and LAS UKIDSS infrared surveys, the DSS-II and SDSS DR7 optical surveys, including the USNO-B1 and GSC II catalogues, the VLSS, TXS, NVSS, FIRST and GB6 radio surveys for information accumulation about the sources. For radio sources that have no detectable optical candidate in optical or infrared catalogues, we additionally looked through images in several bands from the SDSS, LAS UKIDSS, DPOSS, 2MASS surveys and also used co-added different band frames. We reliably identified 76 % of radio sources of the RCR catalogue. For 40 % of radio sources we found significant variation of brightness (m 0.7) in the optical and/or infrared range. According to available photometric and spectral data for about a half of reliable identified sources we defined types of the host galaxies, and 45% of radiosources are quasars, 16 % are galaxies of late types, 22 % are galaxies of early types, 19 % are galaxies of early types with a high activity in radio range. We used the ALADIN and SAOImage DS9 scripting capabilities, interoperability services of ALADIN and TOPCAT, and also other Virtual Observatory (VO) tools and resources such as CASJobs, NED, Vizier and WSA for effective data access, visualization and analysis. Without the VO tools it would have been problematic to carry out our work.
