The Ratio of Two Flux Density Scales at 408 MHz

Abstract
A comparison between two sets of measurements of the flux density of radio sources at 408 MHz confirms that the CKL scale of flux density at this frequency differs significantly from the absolute scale due to Wyllie. To be consistent with the Wyllie scale, CKL flux densities should be increased by $$1\cdot087\pm0\cdot028$$.
