H I - VERSION 11.0

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

h_1.elvlc (energy levels)

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

%  Ken Dere  May 3 2001

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.

%comment: Wavelengths have been calculated the original energy levels from NIST, that include more
          decimal figures than allowed by CHIANTI format.
