(\cite{Repolust2004}), Martins et~al. (\cite{Martins2005b}), and Puls et~al. (\cite{Puls2006}). For all stars without recent line-blanketed models, the calibrations of Martins et~al. (\cite{Martins2005a}) are used. The mass-loss rates are from Monte Carlo radiation-driven wind models (Vink et~al. \cite{Vink2000}). The wind density is given as $\rho_{\rm wind}=\mdot/(R^2 \vinf)$. Where spectral subtypes are not provided, we interpolate. $v\sin i$ are mostly taken from Howarth et~al. (\cite{Howarth1997}).\\ $^1$ Note that the terminal velocity is calculated by multiplication of the escape velocity by the canonical factor of 2.6 (Lamers et~al. \cite{Lamers1995}). \end{table}
