Appendix A: Tables
Tables A.1 and A.2 present the stellar parameters from our HHe analysis of the O Vz and O V samples. Table A.3 presents first estimates for the stars where it was also necessary to use nitrogen lines in the analysis due to weak He i lines and/or strong nebular contamination.
Stellar and wind parameters obtained from quantitative analysis of our sample of O Vz stars.
Stellar and wind parameters obtained from quantitative analysis of our sample of O V stars.
Appendix B: Figures
Figures B.1 to B.3 show the best-fitting models to the observed VFTS spectra for the most important diagnostic lines in this study, i.e., Hγ, He i λ4471, He ii 4541, He i 4686, and Hα.

Fig. B.1
Observed spectra (black dots) and best-fitting synthetic models (red lines) of Hγ, He i λ4471, He ii λ4541, He ii λ4686 and Hα for the O Vz subsample. Each spectrum is labeled with its VFTS number and spectral classification. The cores of strong nebular lines have been removed. |
