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".
