Notes. Columns 8 and 10 give the mean iron abundance derived from Fe i and Fe ii lines, respectively, while Cols. 9 and 11 give the corresponding number of lines. The rest of the columns are self-explanatory. Only the first eight lines are shown here; the full version of the table is available at the CDS.
