Notes. Significance levels above 99% confidence according to the F-test are in boldface, corresponding to the spectra actually requiring extra absorption. Column 1: ObsID and image; Col. 2: photon index; Col. 3: column density in excess of the Galactic value (in units of 1022 cm−2 and placed at z = 1.695); Col. 4: Δχ2 compared to Model pl (Δdof = 1); Col. 5: F-test confidence level. All the errors are computed at a 90% confidence level for one parameter of interest.
