Abstract

We present new flux densities in the range 0.7 cm less-than-or-equal-to lambda less-than-or-equal-to 21 cm for the radio sources in the calibrator list of Baars et al. (1977). Most of these sources show significant variability on the time scale of a decade, with the notable exception of 3C286 and 3C295. We use these sources to link our relative measurements to the absolute scale of Baars et al.; for the other sources we present updated spectra. We assess the suitability of the individual sources for use as flux density calibrators.
