The CHIANTI database has the following primary ASCII files for this ion:
contains the energy levels (in cm-1). It includes both experimental and theoretical values of the levels energies.
Observed energies: Del Zanna, G. 2011, A&A, 533 (EUV lines) Del Zanna, G. 2012, A&A, 546, A97 (soft X-ray) Theoretical energies: Del Zanna, G. & Storey, P. J. 2013, A&A, 549, A42 Note: the theoretical energies are the 'best energies', i.e. are the empirically-adjusted theoretical energies.

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.

For CHIANTI we sum over these sublevels using Eq. 8 of Landman. %comment: These fits reproduce the original data to within 2%. The original data cover the temperature range 1e-6 to 3e-6. %produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration % % Peter Young 12-Jun-2001
