Abstract
Eclipsing binaries with Hipparcos parallaxes are found to define a radiative flux relation for main‐sequence stars in the B6–F0 range about as well as stars with angular diameters and to extend the range to F8. The fluxes of components of binaries showing large intrinsic variations fall well below the curve for other stars and its extension to lower temperatures. Angular diameters of main‐sequence stars obtained with the new generation of stellar interferometers should improve and extend the flux calibration.Keywords
