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.

(2021, ApJ, 257,2,56) for the 3D-3F transitions: 7-60, 9-65 , 8-61 observed by Del Zanna (2012) at 201.49, 197.02, 199.24 Angstroms. We also adopt the new identification given by Zhang et al. (2021) for the 7-331 line at 76.867 Angstroms. We note that several other tentative identifications are given by Zhang et al.

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.
