Resulting ionization structure for the Cloudy photoionization model with parameters log L = 38.0, ne = 3.1 × 107 cm-3, Rmin = 1.5 × 1015 cm, Rout = 6 × 1015 cm, (covering factor) = 0.8, f = 0.3, Teff = 3 × 105 K. The abundance set is the same as that used for V1974 Cyg. Note, in particular, the ionization distribution for Ne and N. See text for discussion.
