Notes. Components are labeled with a letter in ascending order of the outflow velocity (vout), and those with consistent vout are further sub-labeled by a number in descending order of the ionization parameter (ξ). The best-fit parameters of the power-law component (pow) are Γ = 1.79 ± 0.01 with normalization of 4.16 ± 0.06 × 1051 photons s−1 keV−1 at 1 keV.
