Notes. Columns 7 and 9 give the mean iron abundance derived from Fe I and Fe II lines, respectively, while Cols. 8 and 10 give the corresponding number of lines. The rest of the columns are self-explanatory. Only the first five lines are shown here; the full version of the table is available in the electronic edition.
