RZF SURVEY
N.N. Bursov, E.K. Ma jorova, T.A. Semenova, M.G. Mingaliev, A.B. Berlin, N.A. Nizhel'skij, P.G. Tsibulev Sp ecial Astrophysical Observatory of RAS, Nizhnij Arkhyz, 369167, Russia nnb@sao.ru The completed second version of the RZF catalog at 7.6 cm wavelength is presented. A reality of faint and new ob jects of the catalog is evaluated. Radio sp ectra of NVSS ob jects are plotted and a new distribution of sp ectral indices is found. New information ab out a contribution of background of the faint radio sources with inverted sp ectrum and ab out a "sub-mJy" p opulation of the background radio sources in the cm range is found. It is shown that an average sp ectral index of radio sources at the mJy level is flatter, a p ercentage of classical radio galaxies FRI I typ e drops, but the p opulation of ob jects with inversion sp ectra is negligible. Candidates of the most distant radio galaxies (z > 4 - 5) catalog are selected by colors from the SDSS counterparts. A decrease of white noise of radiometers is achieved by a large integration time at pixel that is b elow the level of WMAP exp eriment. The synchrotron comp onent of the foreground Galaxy emission with high accuracy at earlier unstudied angular scales was removed.
