Spectra and best-fit model (blue line) for the Swift (black data points) and 2012 NuSTAR (red) observations. The continuum model includes an absorbed power-law component and a reflected component (grey dotted lines). The reflected component (modelled with XILLVER) also includes the expected Fe Kα emission line at 6.4 keV. The N_H of the neutral absorber, and the normalisation of the primary power law and of the reflected components are all allowed to vary. The model also includes an ionised outflowing absorber, for which the same ionisation is assumed, but the column densities and velocity are allowed to differ in the two spectra. The Swift data were rebinned for plotting purposes.
