Run of the offset in Gaia G magnitude dG with respect to the single star main sequence as a function of the mass ratio q for the stars with masses determined from a combination of 4PMa, RUWE, or a variation in RVs. Filled blue symbols are stars with M_G < 5.8, open red symbols are for fainter stars. The lines are the expected runs of the magnitude offset as a function of q for binaries with primaries of 1.3 M_⊙ and different ages.
