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 +75deg +88deg
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.
