Notes. Distant reflection is modelled using reflext, whose normalisation parameter is fixed to reproduce the observed Fe Kα line (see Sect. 3.3). For both sources, 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. Power-law normalization parameter C is in units of keV^-1  cm^-2  s^-1 at 1 keV; wind column density N_H is given in units of cm^-2, and the ionisation parameter ξ in units of ergcms^-1. The two-phase warm absorber parameters are constrained within the range evaluated with the double Comptonisation model (Table 4). The last two columns give the ratio of the chi-squared value to the number of degrees of freedom and the associated probability.
