Diagrams showing the high end of the distribution of luminosities that we derived for sources in the Bonanos et al. (2010) data set. Left is the uncorrected distribution. Right is the distribution corrected for the completeness of the B10 data set using Gaia data. For comparison, we show the theoretical values (diamonds) for different star formation history scenarios. We also show the number distributions when the brightest source in the WR star system is taken out.
