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.

NIST Physical Reference Data %theoretical energy levels: Bhatia & Landi, 2005, ADNDT, 89, 139 comment: the NIST energy of level 2s2.2p3(2D).3p 3P2 has been associated to level 2s2.2p3(2D)3p 1D2 %produced as part of the Arcetri/Cambridge/NRL 'CHIANTI' atomic data base collaboration % % E. Landi - Sept 2003
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.
