Scientific paper

All-sky Stromgren photometric observations were obtained for 303 speckle binaries. Most stars were in the range of V = 5-8. These data, when combined with ratios of intensities from the CHARA speckle photometry program, will allow the determination of photometric indices for the individual components of binary stars with separations as small as 0.05 arcsec. These photometric indices will complement the stellar masses from the speckle interferometry observations to provide a much improved mass-luminosity relationship.
