Scientific paper

A comparison of three high-sensitivity catalogs of radio sources at meter and centimeter wavelengths, UTRAO (365 MHz), GB (4.85 GHz) and RC (3.94 GHz), has been made. As a result of this comparison the spectral index distribution for about 2000 UTRAO-GB objects in the declination strip of 5 +/-2 deg was computed and a list of about 300 radio sources with a steep spectrum (alpha is greater than 1.1, S varies as nu exp alpha) was obtained. It is shown that the spectral index distributions of unresolved and double radio sources differ. The mean spectral indices for these two classes of objects also differ. A systematic shift in the coordinates between the catalogs (UTRAO-GB) was estimated to be about +1.2 s in right ascension and -14 arcsec in declination.
