XMM-Newton and NuSTAR spectra with the best-fit results of an absorbed power-law model. For plotting purposed only the spectra are binned to a S/N of 5 and 3 for XMM-Newton and NuSTAR, respectively. Bins from the NuSTAR spectrum are only shown up to 50 keV, because at energies above this, no significant bin for the given S/N value is found. Upper panel: EPIC pn (blue), MOS (red) and FPMA/FPMB (yellow) data together with the best fits for the full (0.5−80 keV) energy range (solid line) as well as the hard (2−80 keV) energy range (dashed line). The zoom window shows small deviations between the fits of the full and the hard energy range. Middle panel: data-to-model ratio for the best fit to the full energy range. Lower panel: data-to-model ratio for the best-fit to the hard energy range with extrapolating the model down to 0.5 keV.
