Notes. (1) Model fitted to the X-ray spectrum. (2) Value of the C-stat vs the degrees of freedom. (3) Photon index found or used in the fit. (4) Best-fit value of the corresponding fit-model parameter. (5),(6) Fluxes in the observed 0.5–2 and 2–7 keV bands in units of 10−15 erg cm−2 s−1. (7) Intrinsic luminosity in the rest-frame 2–10 keV band in units of 1044 erg s−1. Errors are reported at the 1σ level and upper limits at the 3 σ level. ◊Fitting model in which Γ was fixed to the best-fit value found in the XMM-Newton data for this QSO by Nanni et al. (2017). ‡For this model we report results for the case with a Kα emission iron line with fixed rest-frame energy of 6.4 keV and width of 0.01 keV. Γ was fixed to 1.8.
