%comment
    Only level 16 does not have an observed energy. I have a 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.

    transition)
%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 FeXIV 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.

%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.
