Notes. We give here the luminosity of the accretors (La) and donors (Ld) of massive semi-detached double-lined eclipsing binaries in the Galaxy and the LMC, and derive the ratio of their respective luminosity to that of single star models (Lsingle) of the same mass and effective temperature. Masses and luminosities are in Solar units.
