Notes. Parameters for the LMC WN stars are from Hainich et al. (2014), whilst the parameters for HD 5980 are from Shenar et al. (2016). The Galactic WN parameters are from Hamann et al. (2006). Masses M⋆ and Eddington factors Γe are obtained from the mass-luminosity relations for both homogeneously H-burning and He-burning by Gräfener et al. (2011). The spectroscopically determined mass-loss rates Ṁ are scaled to a wind clumping factor D = 10. See the discussion in Vink et al. (2011) on the inclusion of WR 136 as a line-effect object.
