Notes. The column density of the cabs component was tied to the column density of the photoionised absorber (see text). kdbb and kgau are the normalisations of the disc blackbody component and Gaussian emission feature, respectively. kTdbb is the temperature of the disc blackbody component. Egau, σ and EW represent the energy, width and equivalent width of the Gaussian feature. and are the column densities for the neutral and ionised absorbers, respectively. ξ, σv, v and S are the ionisation parameter (in units of erg cm s-1), the turbulent velocity broadening, the average systematic velocity shift (negative values indicate blueshifts) and the Sulphur abundance of the absorber in units of solar abundances. F is the unabsorbed flux of the disc continuum between 2 and 10 keV. The width (σ) of the Gaussian emission line gau was constrained to be ≤1 keV in the fits. p indicates that the error of a parameter pegged at the limit imposed.
