Observations of the bright radio sources in the North Celestial Pole region at the RATAN-600 radio telescope

Abstract

A survey of the North Celestial Pole region using the RATAN-600 radio telescope at five frequencies in the range 2.3 to 21.7 GHz is described. Sources were chosen from the NVSS catalogue. The flux densities of 171 sources in the Declination range +75 to +88 are presented; typical flux density errors are 5-10 percent including calibration errors. About 20 percent of the sources have flat spectra or a flat component.

21 pages, 7 figures; to be published in Astronomy and Astrophysics (without last figure with the spectra of the observed sources)
