Observation of the spectrum of nonthermal radio emission of the Galaxy at 200 and 375 MHz

Neasurement results are given for the effective temperature of distributed cosmic radio emission at 200 and 375 MHz along declinations delta=-10 deg, 0 deg, 15 deg 30', 27 deg, 35 deg and 50 deg 30' with the angular resolution of 7 deg x 7 deg. The spectrum of the cosmic radio emission has been defined at points where the given circles delta=const cross the Galaxy plane. In the frames of the method of T-T-diagrams variations of the differential spectrum is investigation of the cosmic radio background at high and intermediate galactic latitudes (b > 10 deg). A variant of the analysis is suggested of T-T-diagrams for regions of the sky, where the spectral index of the galactic radio emission βsub(gal) depends on the direction of observation. A nap has been built of βsub(gal) in the region 12sup(h) <= α < 21sup(h), -10 deg <delta <= 50 deg 30'
