Abstract

Spectra of 197 discrete sources have been obtained in a frequency range 10–1400 MHz. The sources lie at declinations between 0° and +10° and right ascensions from 0–24 h. The spectra have been constructed on the basis of a decametric survey carried out at Grakovo with the UTR-2 radio-telescope, as well as a number of higher frequency surveys performed at Culgoora, Cambridge, Parkes and Ohio. Analysis of the spectrum plots shows that 84% of the spectra are linear (in the logarithmic scale), 11% are characterized by positive and 5% by negative curvature.
