Table 1: Photometry of the stars analyzed in the present paper. The stars are identified by their number in the list of Figer et al. (2002). Observed magnitudes are also from this source. A distance of 7.62 kpc is assumed (Eisenhauer et al. 2005), as well as a uniform extinction A_K=2.8 in the K band (Stolte et al. 2002).
Table 2: Derived stellar and wind parameters. The typical errors are: $\pm$ 3000 K on temperatures, $\pm$ 0.2 dex on $\log \frac{L}{L_{\odot}}$ and $\log \dot{M}$ , 100 km s^-1 on terminal velocities and $\pm$ 30% on abundances. Terminal velocities are adopted from $v_{\infty }$ = 2.6 $\times$ $v_{\rm esc}$ for O stars (except the two O4-6If⁺ supergiants).
Table 3: Comparison between our results and the study of Najarro et al. (2004) for the five stars in common. For each star, the first row gives our results, and the second one the results of Najarro et al. (2004). Only the main parameters are listed.
Table 4: Clumping corrected mass loss rates for the stars in common between the present sample and the sample of Lang et al. (2005).
