Notes. Column 2: redshift assumed (z = 0, 1, or from Table 6). Columns 3 and 4: galactic and intrinsic column density absorption (×1021) in units of cm−2, respectively. The former is kept fixed during the fit. Column 5: photon index from the power-law model. Column 6: normalization parameter (in units of photons keV−1 cm−2 s−1). Column 7: absorbed fluxes (×10−14) in units of erg cm−2 s−1 (0.5−7.0 keV). Column 8: C-stat. value and the number of degrees of freedom. Column 9: the log-evidence (ln𝒵) values for each model. The errors are quoted at the 3σ confidence level from the posterior distributions obtained by BXA except for the flux (which is quoted at 1σ).
