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.

Table A.1

Stellar and wind parameters obtained from quantitative analysis of our sample of O Vz stars.

Table A.2

Stellar and wind parameters obtained from quantitative analysis of our sample of O V stars.

Table A.3

First estimates of stellar and wind parameters from HHeN analysis of the subsample of stars for which He i-ii analysis alone was considered unreliable (see notes in Sect. 4).

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., H_γ, He i λ4471, He ii 4541, He i 4686, and H_α.

	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.
