Notes. Model 1 is a PEXRAV model with all the parameters linked between XMM-Newton and NuSTAR, except for the normalizations. Model 2 has the normalization of the reflection component linked between the XMM-Newton and NuSTAR data, while the primary power law is left free to vary independently, so that the two data sets have two different R parameters. The Γ and high-energy cutoff are linked between the power-law and the reflection component, and between the two data sets. Model 3 includes an ionized absorber with partial covering superimposed on a PEXRAV model with R = 0. Model 4 is a RELXILL_LP relativistic reflection model, where the Ecut is frozen to 300 keV. In Models 1, 2, and 3 the inclination angle is frozen to the default value cos(i) = 0.45.
