        The following A-values were incorrect in the Berrington et al. (2000)
        paper and have been corrected (K.A. Berrington, 2004, private communication)

        The following table lists those transitions for which the new
        A-values (A_2) are more than 30% different from the previous
        CHIANTI A-values (Nussbaumer & Storey 1982).

   %comment:
        The authors estimate that their upsilons are accurate to no better
        than 20%. Note that there are large differences (factors 2-3) over
        the previous R-matrix calculation (Keenan & Norrington 1987, 1991)
        which are attributed to the much larger model used by Berrington et al.

        The CHIANTI fits reproduce the original upsilons to an accuracy of <1.4%.
   %comment: effective collision strengths were provided in the temperature range 4.3 < logT < 6.0.
