Spectra of AGN outflows. Top: selected iron ion abundances (see legend) as a function of t for log() = 6, 10 (left and right panels). The dashed lines show the times corresponding to the spectra shown below. Bottom: absorption spectra for log() = 22 and t = 0, 2, 8, 16 ks (top to bottom, corresponding to the times indicated above and in Fig. 8) and log() = 6, 10 (blue and orange lines). The left and right columns show respectively the Fe L and Fe K bands (i.e. 0.8–1.1 and 6.2–7.2 keV).
