Luminosity histogram of the stellar SED fit. The left and right histograms show the results of the fit to the flux ratio corrected and total photometry, respectively. The full histogram (10 000 points) is shown in dark gray, while the light gray subsamples were obtained thanks to the spectroscopic temperature constraint. The full and dashed lines are the median values of the light and dark histograms, respectively, and have values of 8350 and 8750 L_⊙ for our revised stellar photometry. The histograms were made assuming a distance of 1.5 kpc.
