Beginning of ReadMe : J/other/AstBu/65.42 RCR (RATAN COLD REFINED) catalogue (Soboleva+, 2010) ================================================================================ Ratan-600 7.6-cm Deep Sky Strip Surveys at the declination of the SS433 source during the 1980-1999 period. Data reduction and the catalog of radio sources in the right ascension interval 7h<=R.A.<=17h. Soboleva N.S., Majorova E.K., Zhelenkova O.P., Temirova A.V., Bursov N.N. <Astrophys. Bull., 65, 42 (2010)> =2010AstBu...65..42S ================================================================================ ADC_Keywords: Surveys ; Radio continuum ; Radio sources Keywords: radio continuum: general - surveys - radio sources: general - radio sources: identifications Abstract: We use two independent methods to reduce the data of the surveys made with RATAN-600 radio telescope at 7.6cm in 1988-1999 at the declination of the SS433 source. We also reprocess the data of the "Cold" survey (1980-1981). The resulting RCR (RATAN COLD REFINED) catalogue contains the right ascensions and fluxes of objects identified with those of the NVSS catalogue in the right-ascension interval 7h<=RA<=17h. We obtain the spectra of the radio sources and determine their spectral indices at 3.94 and 0.5GHz. The spectra are based on the data from all known catalogues available from the CATS, Vizier, and NED databases, and the flux estimates inferred from the maps of the VLSS and GB6 surveys. For 245 of the 550 objects of the RCR catalogue the fluxes are known are known only at two frequencies: 3.94GHz (RCR) and 1.4GHz (NVSS). These are mostly sources with fluxes smaller than 30mJy. About 65% of these sources have flat or inverse spectra (alpha>-0.5). We analyse the reliability of the results obtained for the entire list of objects and construct the histograms of the spectral indices and fluxes of the sources. Our main conclusion is that all 10-15mJy objects found in the considered right-ascension interval were already included in the decimetre-wave catalogues. Description: From 1980 till 1999 7 surveys of 40' width sky strip, centred on SS433 declination have been carried out on the radio telescope RATAN-600. Observations were spent on 7.6cm wavelength in the range of right ascensions 4h<RA<22h and on 31cm in an interval 4h<RA<13h. On a basis of the given observations 1980-1981 on 7.6cm wavelength (experiment "Cold") has been obtained the RC catalogue of radio sources. Re-processing of the surveys data in the range of 7h<RA<17h is conducted for improvement of coordinates and flux densities of the RC catalogue sources The results of data processing by two methods described in the paper are included in the RCR catalogue. The NVSS catalogue was used as reference one. The RCR table includes NVSS coordinates of sources, differences between NVSS right ascension and right ascension obtained by the first and second method of scan data processing, and also errors, flux density on 7.6cm or 3.9GHz (also defined by two methods) and errors. We fitted available flux density data by curves and obtained 3.94GHz and 0.5GHz spectral indexes for the whole source list. At construction of spectra in addition to the available data of known catalogues we used estimated values of flux density obtained on the VLSS and GB6 images. Estimated values of 4.85GHz flux density have allowed to confirm reliability of weak objects allocation on the scans. In total in a strip of right ascensions 7h<RA<17h was evolved 550 objects, from them are 18 blinds and 15 double sources. All of them are identified with objects of the NVSS catalogue.
