  3. fe_25d.wgfa (radiative data)
  4. contains wavelengths, gf and A values of the transitions. The wavelengths are based on the experimental energy levels and should be the best available. Wavelengths calculated from the theoretical energies are of an indeterminate accuracy and their values are presented as negative values of the calculated wavelength.

    %comment: theoretical energies have been used as experimental values for the dielectronic transitions
    %comment: V4.02 wavelengths have been replaced with Safronova's values to better match the 
              observations (E.Landi - Oct 2003).
