       Only level 16 does not have an observed energy. I have placed in
       the third energy column a recommended value for the energy value of
       this level, based on the theoretical and observed splittings of the
       4F levels. It is this energy value which is used to compute the
       wavelengths of transitions involving level 16 given in the .wgfa
       file.

   %comment: This set of radiative data were calculated using the FeXIV model
        described on p.679 of Storey, Mason & Saraph (1996, A&A 309, 677)
        and labelled by them as the "extended basis". In Storey, Mason &
        Young, this basis is referred to as "basis 3".
        The wavelengths for transitions involving level 16 were derived
        using the "best guess" energy for level 16 given in the 3rd energy
        column of the .elvlc file.
   %comment: added transition experimental A-value 2-5 from Traebert et al 1988 (E. Landi, Sept. 20, 2006).

  Collision strengths :

   filename: fe_14.splups
   %effective collision strengths: Storey P.J., Mason H.E., Young P.R., 2000, A&ASS 141, 285
   %comment: effective collision strengths were given in the temperature range 5.5 < Log T < 7.2
   %effective collision strengths (1-2 transition): Storey PJ, Mason HE, Saraph HE, 1996, A&A 309, 677
   %comment: effective collision strengths for the 1-2 transition were given for temperatures lower than Log T = 7.0
   %comment:
       Although data for the 1-2 transition was calculated by Storey, Mason
       & Young (1999), that presented in Storey, Mason & Saraph (1996) is
       considered more accurate.

       Only transitions involving levels 1, 2 and 21 are tabulated here. These
       are the only levels with significant population. Inclusion of all of the
       other Fe XIV transitions has negligible effects on the level balance of
       the ion.

       For the gf values, I have used those calculated in the "basis 1" model
       of the ion, which is the one used for the collisional calculation.
       Note that the gf values in the .wgfa file are from the more accurate
       "basis 3" model.

 Regenerated to use the standard ADAS temperature set.

 Add the transitions in the CHIANTI source which have a transition
 probability but no accompanying effective collision strength and
 set these upsilons to zero.
