logT_eff-log g diagram for SMC (LMC, Galactic) sample stars in the top (middle, bottom) panels. Filled (open) symbols are for the XShootU (complementary) sample. Left panels are for Geneva tracks (Eggenberger et al. 2021 for the LMC, Georgy et al. 2013 for the SMC, and Ekström et al. 2012 for the Galaxy), middle panels for tracks from Brott et al. (2011a), and right panels for tracks from Grasha et al. (2021). We show tracks for initial rotational velocities of about 300 km s⁻¹ and, in the case of those of Brott et al., also 170 km s⁻¹ (in pink). Surface gravity has been corrected for the effect of rotation in the sample stars. The cross in each panel indicates typical error bars that are taken from Fig. 1.
