Abstract:
The results of 0.97, 2.3, 3.9, 7.7, 11.1 and 21.7GHz observations of
a complete sample of radio sources obtained on the RATAN-600 radio
telescope are presented. The sample is comprised of sources from the
4.85-GHz MGB survey, and contains all sources at declinations
10-12.5 degrees (J2000) with galactic latitudes |b|>15 degrees and
flux densities S(4.85)>200mJy. Optical identifications have been
obtained for about 86% of the radio sources with flat spectra and 59%
of those with steep spectra.
