Notes. The indicated values are adopted from Hainich et al. (2014), with terminal wind velocities from Niedzielski & Skorzynski (2002), Niedzielski et al. (2004). The mass-loss rates have been determined for a wind clumping factor of D = 10. Masses are derived from the observed luminosities using the M(L) relations for He stars from Gräfener et al. (2011).
