Abstract
A method based on Landolt photometry in B and V is developed to correc t for a wavelength independent offset of the absolute flux level of op tical spectrophotometric standards. The method is based on synthetic p hotometry techniques in B and V and is accurate to similar to 1%. The correction method is verified by Hubble Space Telescope Faint Object S pectrograph absolute fluxes for five calibration stars, which agree wi th Landolt photometry to 0.5% in B and V.
