Notes. Column (1): model name; Col. (2): photon index; Col. (3): column density in excess of the Galactic value (units of 1022 cm−2); Col. (4): high-energy cutoff rest-frame energy (keV); Cols. (5) and (6): rest-frame energy (keV) and equivalent width (eV) of Fe Kα emission line; Col. (7): reflection fraction; Col. (8): Cstat. (degrees of freedom ν). The line width of the Fe Kα is set to σ = 0.1 keV rest frame. All errors are computed at the 90% confidence level for one parameter of interest. Model list: Model pl = phabs*zphabs*zpo; Model acutpl = phabs*zphabs*zcutoffpl; Model acutpl+Kα = phabs*zphabs*(zcutoffpl+zgauss); Model axill = phabs*zphabs*xillver. All models include Galactic absorption (NH = 4.2 × 1020 cm−2).
