Notes.
[X] denotes the logarithm of the mass fractions relative to the solar values from Asplund et al. (2009). Columns I–VIII list the number of NLTE levels and lines (first and second number of each table entry, respectively) of the respective ionisation stages of the model atoms. For Cr, Mn, Fe, and Ni, these are superlevels and superlines; see text.
