ABSTRACT

Radio sources detected at 3.94 GHz in RATAN-600 observations made in 1980–1981 (the KHOLOD Survey) have been identified with objects from the NVSS catalog down to 5 mJy at 1.4 GHz, and their spectral indices have been estimated. Of the 1311 NVSS objects in the KHOLOD survey region, 836 are present in both catalogs. The average flux density of the common objects is 40 mJy, and the median flux density is 14 mJy. The average spectral indices of these objects for four flux-density intervals were calculated. The average spectral index grows with flux density. The fraction of objects with inverted spectra is 2–4%, and the average flux density of these sources is about 10 mJy. Optical identifications of the NVS S objects in the KHOLOD survey region have been carried out to R=20.5m using the Palomar plates. About 20% of the radio sources are identified with optical objects in all the radio flux-density intervals. More... »
