Notes. log gtrue is the surface gravity corrected for centrifugal effects. The secondary Teff diagnostics used in parallel with the He i/He ii ionization equilibrium is indicated for each star. For three stars, two parameter sets are provided because we had problems to reach a simultaneous fit for all considered lines from three ionization stages. For N11-026 and N11-060, the first entry is our preferred one, and the second entry is a (disfavored) alternative, whilst for N11-031 we consider both solutions as possible (see Sect. 5). Brackets around v: derived from scaling via vesc. Asterisks following vmic: value obtained in parallel with nitrogen abundance. For errors, see text.
