Description
We present the additional list of radio sources of the RCR (RATAN Cold Refined) catalog. The sources was obtained on the observation data of the COLD experiment which included a series of surveys carried out in 1980-1999 on the RATAN-600 radio telescope. This part of RCR catalogue contains the right ascensions, integrated flux densities at 7.6cm (3.94GHz) and their spectral indices 3.94 and 0.5GHz of 269 objects detected in the right-ascension interval 2h<R.A.<7h and also additional 24 radio sources found in only one survey and 3 transient candidates in the right-ascension interval 2h<R.A.<17h. We constructed radio spectra of the sources using data of the catalogues from CATS and VizieR databases which the strip of COLD surveys overlays, and, in cases of weak sources, for this purpose we used the flux density values estimated from VLSSr, GLEAM, TGSS, and GB6 survey maps. 6% of the sources, which are mostly weaker than 30 mJy at 3.94GHz, have flux density data only at two frequencies - 1.4 and 3.94GHz. About 30% of these sources have flat or inverse spectra (alpha>-0.5) at 3.94GHz. We verified the reliability of identifications of the sources detected in the scans by comparing the coordinates and integrated flux densities with the corresponding parameters of the sources of the NVSS catalogue. In the central 10'-part of the strip at 10mJy level completness of the catalogue is about 90% and we found no objects that lack in decimeter-wave catalogues.
