... 1Wills Accurate measurements of relative flux density have been made between frequencies of 468 and 5009 MHz for 300 radio sources selected from Parkes catalogue. ... Excluding the incertainties in scaling these flux densities to an absolute system, rms errors vary from 0.24 Jy and 2.4 % at 635 MHz to 1.8 % at 2700 MHz; uncertainties in "absolute" scaling are thought to be about 45 %. ... Some sources whose spectra may be useful for flux density calibration are noted. ...
