EPIC pn (top) and Suzaku XIS+PIN (bottom) spectra unfolded against the best-fit model described in Table 6, along with data-to-model ratios. The intrinsic continuum emission is modelled with optxagn (dotted-dashed black line); two reflectors are modelled with xillver, a highly ionised (dashed blue line) and a cold, absorbed one (solid magenta line). The total model is plotted in red.
