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.
Theoretical energies: Mao, J. , Badnell, N. R., Del Zanna, G., 2020, A&A, 634, A7 DOI: 10.1051/0004-6361/201936931 Observed energy levels as estimated by Edlen B., 1985, Physica scripta, 31, 345. Produced as part of the 'CHIANTI' atomic data base collaboration by Giulio Del Zanna, Aug 2020 -1
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.
