Notes. Cluster and association members are listed in the upper and field stars in the lower part. In addition to standard abbreviations, gc is the centrifugally corrected surface gravity, and Vt the macroturbulence. Boldfaced numbers in Col. 11 indicate Vr measurements that are first (and thus unique) for the corresponding stars. By convention, [N] = 12 + log(N/H). Typical errors: <0.4 mag in MV; <0.17 dex and 20% in log L∕L⊙ and R⋆, respectively; ±0.2 dex in [N], and ±0.02 in YHe. An uncertainty of ±0.13 dex (Hα in emission) and <±0.23 dex (Ha in absorption) was estimated for log Ṁ (unclumped). ( *) marks v∞ adopted from the calibrations by Kudritzki & Puls (2000); (a) indicates a HeII 4686 mass-loss rate inconsistent with the wind emission implied by Hα, directly pointing to the presence of wind inhomogeneities (see text).
