Notes. ΓS and kTH are fixed at values 2 and 100 keV, respectively. Distant reflection is modelled using reflext, whose normalisation parameter is fixed to reproduce the observed Fe Kα line (see Sect. 3.3). Two Gaussian functions are included in the model, for the narrow Fe Kβ and the broad Fe K emission line, with parameters fixed as in Table 2. NTHComp normalization parameters C are in units of keV-1 cm-2 s-1 at 1 keV; warm absorber column density NH is given in units of cm-2, and ionisation parameter ξ in units of ergcms-1. Fixed parameters are marked by (F). The last two columns give the ratio of the chi-squared value to the number of degrees of freedom and the associated probability.
