   %A-values, gf-values: Nussbaumer H., 1977, A&A 58, 291
   %comment: The Nussbaumer A-values are used for the transitions between levels
      1 to 5, i.e., the forbidden and intercombination transitions. Nahar
      did not calculate A-values for these transitions.

      Nahar only gave gf values. These were converted to A-values by using
      the experimental energy separation.

      Table A of Nahar gives a useful comparison of his gf values with
      those from previous calculations and experiment.
   %comment: correction on 11-Jun-03, Peter Young
      The 1-3 A-value was incorrectly listed as 4.550E-03. The correct value
      of 4.550E+03 has now been inserted. It affects line at 2335 A (Error spotted
      by Sergei Lamzin.)
