Notes. We allow for cross-calibration uncertainties between the two NuSTAR spectra and the simultaneous XMM-Newton/pn spectrum by including in the fit a cross-normalisation constant corresponding to CNuSTAR A and CNuSTAR B for NuSTAR FPMA and FPMB spectra, respectively. The fit with the default values for E(B − V), the AGN distance, and MBH are reported in Col. 1. The other columns report the fit results when we vary one assumption from the fixed values (marked in bold) compared to the default values of E(B − V), the AGN distance and MBH. (f) means that the parameter value is fixed.

BH mass from reverberation mapping (Peterson et al. 2004) using the calibration of the M–σ⋆ relation for AGNs based on high-luminosity quasars hosts (mean virial factor: ⟨f⟩=4.31 ± 1.05) from Grier et al. (2013), Bentz & Katz (2015).
BH mass from reverberation mapping (Peterson et al. 2004) using the calibration of the M–σ⋆ relation for classical bulge galaxies (mean virial factor: ⟨f⟩=6.3 ± 1.5) from Ho & Kim (2014). See Sect. 5.1.2 for a detailed explanation.
The log(Lbol/LEdd) ratio is equal to log(Ṁ/ṀEdd), where Ṁ is the absolute accretion rate (see Eq. (1)) and ṀEdd is the Eddington accretion rate.
