Notes. Fixed parameters are marked with an asterisk, parameters adopted from the fit to the 2006 XMM-Newton observation with . The photon index of the reflection component is tied to that of the high-energy power law. The model also includes an unresolved Gaussian line at Ec = 0.826 keV identified as Fe L xvii and a O viii radiative recombination continuum (RRC) with an edge energy of 0.871 keV.
