Notes. The fitting was carried out over the 0.3–7 keV observed-energy range because the data are background dominated above 7 keV. 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: covering fraction of the extra absorption; Col. 5: logarithm of the extra-absorption ionization parameter (erg s−1 cm); Col. 6: observed redshift of the extra absorption; Col. 7: reflection scaling factor; Col. 8: energy of the narrow emission line (units of keV); Cols. 9 and 10: Δχ2, Δν compared to Model pl (χ2 = 167.4, ν = 102); Col. 11: 
. The energy width of the emission line is set to 0.01 keV. All the errors are computed at a 90% confidence level for one parameter of interest. Model list: Model pl = phabs*zpo; Model pl_a = phabs*zphabs*zpo; Model pl_pca = phabs*zpcf*zpo; Model pl_wa = phabs*warmabs*zpo with z ≡ zq; Model pl_pca_el = phabs*zpcf*(zpo+zgauss); Model pl_pca_pex_el = phabs*zpcf*(zpo+pexrav+zgauss) with Γ = 1.9. All the models include the Galactic absorption (NH = 5.1 × 1020 cm−2).
