Notes. The accretion disk wind inclination angle and mass outflow rate are kept constant between epochs, while the ionizing hard X-ray luminosity Lx/LEdd is tied to the unabsorbed 2 − 10 keV flux for each epoch. Units: power-law normalization N1 keV [10−4 photons keV−1 cm−2 s−1]; column density NH [1022 cm−2]; ionization parameter ξ [erg cm s−1]; terminal velocity υ [c]; flux f [10−12 erg s−1 cm−2]; luminosity L [1043 erg s−1]. The unabsorbed flux is corrected for both intrinsic and Galactic absorption, as is the luminosity.
