Notes. Columns are star’s ID, spectral type from Vink et al. (2023), effective temperature, surface gravity, surface gravity corrected for centrifugal acceleration, luminosity, projected rotational velocity, macroturbulent velocity, microturbulent velocity, abundance of He, C, N, and O by number. Typical uncertainties on V sini and vmac are of the order 10–20 km s−1. For vturb 5 km s−1 is a reasonable error as explained in Sect. 2.3. Uncertainties on Teff and log g are correlated and typical values are shown in Fig. 1. An error of about 0.15 dex on luminosity is a typical value.
