Notes. The subscript “h” and “l” refer to model components applied to spectra taken during high- and low-hardness periods, respectively. We list best-fit results for three cases: no ties between parameters describing low- and high-hardness spectra (“no ties”), same equivalent hydrogen column width of absorption for low- and high-hardness spectra (“tied NH”), and same photon index for low- and high-hardness spectra (“tied Γ”).
