Notes. In Cols. 2 and 3 the number of levels used in the non-LTE calculations are given in packed and unpacked form. Columns 4 and 5 list the number of lines used for solving the rate equations (the statistical equilibrium for all important ions) and for the line blocking and synthetic spectra calculations, respectively.
