Average multiplicative correction of GALEX fluxes from direct comparison to CALSPEC SEDs. Black data points connected by dotted lines are the results from the two matched stars in the FUV and four stars in the NUV, while the red diamonds connected by solid lines are the weighted average correction. Results for HZ4 dive down below unity longward of 2575 Å but have little weight. Error bars reflect the combination in quadrature of the GALEX and CALSPEC statistical uncertainties.
