Notes. For each parameter the Δ column gives the mean difference “this work” − “reference”, σ the dispersion between the two series and ∇ the slope from the linear fit. The three lines are for the OBA (T_eff > 8000 K), FGK (4000 < T_eff ≤ 8000 K) and M (T_eff ≤ 4000 K) spectroscopic types, respectively. The statistics were computed discarding the outliers.

^(a)

Number of compared spectra

^(b)

The Δ and σ of T_eff are in K, except for the OBA stars, where these statistics are given in percent.
