Anyway, we consider the results sufficient to conclude that we do not see any substantial differences. In a final step, we like to illuminate the primary dependencies of the mean ionization fractions for our sample, in the same spirit as performed by Lamers et al. In contradiction to their findings, however, we see from Fig. To understand this difference, let us proceed as follows. Average values for mean ionization fractions obtained from different authors and different samples.
Errors relate only to the standard deviation from the mean, see text.
We find a similar behaviour in both cases. See text the mean density is such strongly correlated with and that the extra dependency on stellar radius should be very weak. This primary dependence of mean wind density on effective temperature, if one considers a single luminosity class in a well defined spectral range, can be actually also found in Fig. 2 of Lamers et al. In so far, we will compare here only the dependence on with the according analysis by Lamers et al.
