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.
