J/AZh/71/684   Optical Identification of RC and UTRAO Catalogs (Soboleva+, 1994)

Optical Identification of the Objects of RC and UTRAO Catalogs on Enlarged Palomar Sky Atlas Prints Soboleva N.S., Parijskij Yu.N., Naugolnaya M.N. <Astron. Zh. 71, 684 (1994)> =1994AZh....71..684S =1994ARep...38..605S
ADC_Keywords: Radio sources ; Cross identifications Description: Two hundred and forty radio sources that are common for RC (RATAN-600) and UTRAO (VLA, Douglas J.N.+, 1980PAUTx..17....1D) catalogs were identified on the enlarged prints of the Palomar Sky Atlas. The number of identified radio sources with flux density between 15 and 300 mJy drops with decreasing flux density in the centimeter wavelength range. File Summary:
