Hertzsprung-Russell diagram of our SMC sample of stars with temperatures and luminosities resulting from the fit. Points with a red border indicate stars with unreliable parameters. We overplot the evolutionary tracks (thin solid gray lines) and isochrones (thin dashed gray lines) of Brott et al. (2011). The solid black line indicates the zero-age main sequence. The points are labeled with the name of the object in a small font that is visible when zoomed in.
