Absolute Measurements of the Flux of Cassiopeia a and Taurus a at 1.87 Centimeters

Revised values of the flux at 16 GHz of Cas A and Tau A are presented. The flux of Cas A is 343 f.u. +19 f.u. (3 a), and the flux of Tau A is 447 f.u. +30 f.u. (3 a). The presence of a previously reported variation in the flux of Tau A has been attributed to an instrumental effect.
