Description:
Two hundred and forty radio sources that are common for RC (RATAN-600)
and UTRAO (VLA, Douglas J.N.+, 1980PAUTx..17....1D 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.
