Observed broadband NGC 5548 SED. The solid red line shows the model obtained for h = 46 r_g. The dashed green line shows the unabsorbed best-fit model (i.e. by removing all Galactic and intrinsic neutral and warm absorbers). The dash-dotted black lines show the various spectral components. Empty circles indicate the data points that we did not consider during fitting, to avoid contamination from the BLR (see Sect. 4 for details). The grey, blue, and orange data points indicate the three X-ray spectra we used in the fitting.
