Notes. The numbers in parentheses refer to the model with the high X-ray illumination, which requires the inclusion of higher ionization stages. The numbers in parentheses refer to the model with the high X-ray illumination, which requires the inclusion of higher ionization stages. (a) Number of transitions with non-negligible oscillator strengths as considered in the radiative transfer calculations. (b) For Fe, the large numbers refer to superlevels and superline transitions that are used to cope with the enormous number of lines and transitions given as smaller numbers in brackets. The atom listed as Fe here is a generic element that also includes the iron group elements Sc, Ti, V, Cr, Mn, Co, and Ni (see Gräfener et al. 2002, for details).
