J/AZh/73/835    Identifications of objects from RC Catalog   (Fletcher+, 1996)

Identification of the Objects from the RC catalog with accuracy exceeding 1" using the Palomar Prints and VLA maps from the MIT archive. Fletcher A., Conner S., Crawford F., Cartwright J., Burke B., Pariiskii Yu.N., Soboleva N.S., Kopylov A.I.,Temirova A.V., Verkhodanov O.V., Naugol'naya M.N. <Astron.

ADC_Keywords: Radio sources ; Cross identifications Description: Results from a continuing program for identification of sources from the RC catalog (from observations with the RATAN-600 radio telescope) with the APM (Automatic Plate Measuring) Northern Sky Catalogs available via the Internet are presented. The coordinate accuracy for the optical objects is better than 1". File Summary:
