Flux Calibration of the MMA

M.A. Holdaway [1]

February 20, 1996

Keywords: flux calibration, amplitude calibration, total power

I propose that the MMA achieve accurate flux scale calibration by observing extended sources of constant or predictable flux, such as planets or compact HII regions, in total power. The total power flux scale set by this primary flux standard can be used to measure the total power flux of a bright, time variable quasar. Since the quasar is compact to all baselines and frequencies of the MMA, interferometric observations of this bright quasar, whose flux is known through the total power observations, will set the flux scale for interferometric observations.
