Table 10: Effective temperature scales of B-type stars in the Milky Way, LMC and SMC for different luminosity classes. These scales are based on parameters presented in this paper and Paper IV, as well as a number of SMC stars from Dufton et al. (2005). The values in parenthesis are those for which we have no objects in the spectral type bin but for which we could interpolate. The $T_{\rm eff}$ values are presented in units of K.
