Hertzsprung-Russel diagram of all systems with Gaia measurements for the effective temperature and luminosity with adjoining histograms showing the density distributions for luminosity and temperature for each sub-class for each panel. The upper-left panel also shows solar metallicity (Z=0.014) evolutionary tracks from 1.2 to 9 M_⊙ from M24 (solid red/yellow) computed using an exponentially decaying core-boundary mixing prescription (f_ov of 0.015) along with full 1.3 M_⊙, 5 M_⊙, and 9 M_⊙ MIST tracks (grey dashed, Choi et al. 2016). The coloured variation in each of the M24 tracks shows the effect of varying the rotation from 5-55% (red-yellow) of the initial Keplerian critical rotation frequency.
