Hertzsprung–Russell diagram overlapped with Geneva stellar evolutionary tracks at solar metallicity of ,italic>Z = 0:014. The nonrotation(solid lines) and rotation (V/V_c = 0.40; dashed lines) models of 7 to 40 M_⊙ are color coded. Top: luminosity is converted by using a constant bolometric correction of BC_KS = 2.69, while T_eff is derived following the method used in Neugent et al. (2012). Most of the outliers can be well explained by the combination of variability and reddening as shown by four error bars. Bottom: luminosity and T_eff are converted by using the exact same method used in Neugent et al. (2012). See text for details.
