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

na_10.elvlc (energy levels)

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

 
%experimental energy levels: Martin,W.C., Sugar,J., Musgrove,A., Dalton, G.R., 2000,
     NIST Database for Atomic Spectroscopy, Version 1.0, NIST Standard Reference Database 61.
%experimental energy levels (1s2p 3P): Curdt, W., Landi, E., Wilhelm, K., Feldman, U., 2000, Phys.Rev.A, 62, 022502
%Comment: the 1s2p 3P energies are calculated using the 1s2s 3S level as reference. 
%Comment: 1s2p 3P1 energy has been calculated from the 1s2s 3P0 level using the NIST level separation.
%theoretical energy levels: interpolated using He-like ions from C V to S XV.

na_10.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.
