Notes. L is the luminosity from the literature and L_G is the luminosity derived from the GRAVITY spectra. ∆ is their difference in units of standard deviations of the GRAVITY-derived luminosity σ_G. An additional systematic uncertainty of 10% (~0.05 dex) has been added in quadrature to the GRAVITY-derived luminosity to account for flux calibration errors. M_dyn is the dynamical mass from the literature and M_evo is the mass derived from evolutionary models based on the GRAVITY luminosity.
