Confidence contours, at 68%, 90%, and 99%, of the logarithm of the ionization parameter (﹩\mathrm{log}\,\xi ﹩) vs. the column density (NH) around the best‐fitting photoionized absorber corresponding to Fig. 10 (see also Figs. 3 and 11). The HEG and MEG spectra were binned at 0.04 Å. See § 5 for details.
