The Radio Spectra of Sources in the Fourth Cambridge Catalogue, II

The Radio Spectra of Sources in the Fourth Cambridge Catalogue, II

Using observations at 38, 178, 610.5 and 1417 Mc/s the radio spectra of sources in the declination range 40°–44° of the 4C catalogue have been determined. Comparing the spectral indices of sources in lists compiled at 38, 178 and 610.5 Mc/s, it is seen how the mean spectral index of a list of source...

Zusammenfassung:Using observations at 38, 178, 610.5 and 1417 Mc/s the radio spectra of sources in the declination range 40°–44° of the 4C catalogue have been determined. Comparing the spectral indices of sources in lists compiled at 38, 178 and 610.5 Mc/s, it is seen how the mean spectral index of a list of sources selected according to flux density at a given frequency is a function of that frequency.
