Notes. The column “Level” lists a total number of individual levels and superlevels. The column “Data” gives the source of data for NLTE (a) and for line radiative force calculations (b) in a format of a∕b. The column “Range” gives the temperature range (in kK) in which the given ion is included in calculations. A blank item means that the ion is always included.
