The CHIANTI database consists of the following primary ASCII files for this ion:

fe_17d.elvlc (energy levels)

contains the energy levels in cm^(-1) It includes both experimental and theoretical values of the levels energies.

 
%Energy levels (below ionization): Shirai,T., Sugar,J., Musgrove,A., Wiese,W.L., 2000, J.Phys.Chem.Ref.Data, Monograph 8
%Energy levels (above ionization): Mendoza, C., Kallman, T.R., Bautista, M.A., Palmeri, P., 2004, A&A, 414, 377
%Comment: some energy levels from the NIST database, version 2.0, have been renumbered
        in order to match the identification given by Bhatia and Doschek
        and their theoretical energy levels. In particular, the following changes
        have been made:
                        NIST  -->  CHIANTI
                         12   -->     9
                         13   -->    12
                          9   -->    13
%Comment: the theoretical energies from Mendoza et al have been used as experimental ones.
%Comment: the LS notation for energy levels has been taken from Mendoza et al.

fe_17d.wgfa (radiative data)

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.

fe_17d.splups (electron collision data)

contains the spline fits to the electron collision strengths scaled according the rules formulated by Burgess and Tully (1992). Accurate replication of the temperature averaged collision strength over a wide range of temperatures can be accomplished with the data in this file.
