Hertzsprung-Russell diagram for the nine Of stars in the N 206 superbubble in the LMC. The evolutionary tracks and isochrones are based on rotating (V_rot,init ~ 100 km s^-1) evolutionary models presented in Brott et al. (2011) and Köhler et al. (2015). Different luminosity classes are denoted using rhombus, squares, triangles, and circles for luminosity class Vz, V-IV, III-II, and I, respectively. The position of the secondary components of N206-FS 131 and N206-FS 180 are also marked in the diagram with a cross symbol.
