Notes. In all models q = 3, a = 0.998 and r_out = 1000. monaco was computed for a fixed wind geometry and the same inclination angles are assumed for the disc and wind, so this component does not add any free parameters in our fitting procedure. The model is fitted jointly to the three states with linked i and Z_Fe. We give χ²/DoF for the joint fit and contribution of individual states to the total χ². The best-fit values and parameter uncertainties given in the table correspond to binning (1); the differences in the best-fit values with binning (2) are negligible. ^(a) Symbol “+∞” denotes r_in approaching r_out = 1000.
