Abstract

RECENT observations at nine frequencies between 38 and 3,200 Mc/s have been compiled and used to determine the spectra of 160 discrete radio sources 1. Although, in general, the spectra can be represented by a simple power law, at least for frequencies below 1,420 Mc/s, in a few cases the spectral index shows a considerable dependence on frequency.
