The shape of radio spectra of spurs between 38, 408 and 1420 MHz.
Abstract
The spectra of the North Polar Spur (NPS), the Spurs in Aquarius, Pegasus and Taurus were derived from the spectral indices between 38, 408 and 1420 MHz. The data were reduced to the case of scaled aerials with HPBW of 7°25×8°25. Using the second order polynomial approximation, mathematical spectra have been computed. They appeared similar for all three spurs. Clear maximum of relative flux for the NPS and for the Spur in Taurus is seen at about 14 MHz, for the Spur in Pegasus maximum is at about 17 MHz while for the Spur in Aquarius is near 19 MHz.
