ADC_Keywords: Radio sources; Surveys Description: The main catalog contains positions and flux densities for 8511 sources detected in the Zelenchuk 3.9 GHz Survey with declinations between 0 and 14 degrees. The survey was originally published in Amirkhanyan et al. 1989, MIR Publ., Moscow, and contained 8511 sources. The machine version has been cleaned from a few spurious sources by the authors. The angular resolution is (RA x DEC) 70"/cos(decl) x 50'. The survey is 95 percent complete to the limiting flux density 50 mJy, except near the boundaries of the declination zone. A supplementary catalogue of 2946 radio sources observed during Zelenchuk survey at 3.9 GHz in the flux density from 40 to 50 mJy within the declination range 0-14 degrees are presented. ratan is the first results of the deep search survey over a portion of the celestial sphere with the radio telescope RATAN-600 at several cm-wavelengths. The catalogue contains 691 radio sources at 3.9 GHz. Fluxes at the frequencies 3.9, 4.8, 7.5 and 11.2 GHz have been measured for the complete sample of the radio sources from the Zelenchuk survey. The sample contains all sources with S > 200 mJy in the 4-6 degree declination range. File Summary:

Note (1): In the catalogue, the declination was given only as hours and minutes, due to the sparse resolution in declination. A rough approximation to positional errors is d(DEC) ∼ 0.45'/S[Jy] Note (2): A crude estimate of the flux density error is dS = sqrt((0.1)**2 +(S/10Jy)**2 ) Jy The errors in flux density and position may be estimated using the following table: Flux S(Jy) Error S(mJy) dPA cosD (sec) dD (') -------------------------------------------------------- 0.05 11 0.67 9.1 0.07 12 0.50 6.5 0.10 14 0.37 4.6 0.20 22 0.24 2.3 0.30 32 0.21 1.5 0.40 41 0.20 1.1 0.50 51 0.20 0.9 0.70 71 0.19 0.7 1.00 100 0.19 0.5 -------------------------------------------------------- where dPA is the difference in right ascension, cosD is the cosine ascension, and dD is the difference in declination."
