J/AZh/84/227  RATAN-600 Zenith-Field sky survey (RZF) catalog (Bursov+, 2007)

A RATAN-600 Zenith-Field sky survey. Catalog of radio sources. Bursov N.N., Parijskij Yu.N., Maiorova E.K., Mingaliev M.G., Berlin A.B., Nizhel'skii N.A., Glushkova I.A., Semenova T.A. <Astron. Zh. 84, 227 (2007)> =2007AZh....84..227B =2007ARep...51..197B
ADC_Keywords: Radio sources ; Surveys Abstract: A catalog of radio sources detected in a deep RATAN-600 survey is presented. The catalog was obtained in the region 0h≤RA(2000.0)≤24h, Dec(2000.0)=41:30:42±2, at the declination of the bright radio source 3C 84. There were nine sessions of multi-wavelength observations at wavelengths lambda=1-55cm, and more than 300 daily scans were accumulated at each wavelength. This is the first stage in the reduction of an extensive database accumulated by the Cosmological Gene Project. The RATAN-600 Zenith Field (RZF) catalog was obtained at the central wavelength of 7.6cm, and contains 437 radio sources, virtually all of which have been identified with NVSS objects. Most of the flux densities for the catalog sources are above the 5 level. Noise from faint (mainly new) background sources at a level of about 0.8mJy has been detected. The minimum flux density of the catalog, 2.5mJy, is comparable to the flux-density limit of the NVSS catalog. The catalog is more than 80% complete for sources with flux densities >3mJy. Description: The observations were carried out from 1998 to 2003 on the Northern sector of the RATAN-600 at the declination of the bright source 3C 84, in nine scans spaced by 12' in the sky, so that the entire area covered is 0h≤RA2000.0≤24h, Dec2000.0=+41:30:42±60". Nine observing sessions at wavelengths lambda=1.0-55cm were conducted, leading to a total of more than 300 days of observations. File Summary:
