Notes. Columns: (1) WISSH ID; (2) SDSS ID; (3) Redshift (from Saccheo et al. 2023); (4) Galactic column density (in units of 10²⁰ cm⁻²); (5) X-ray photon index; (6) Intrinsic column density (in units of 10²² cm⁻²). Upper limits indicate that the addition of an intrinsic absorption component is not significantly required (i.e. < 95% c.l.); (7) Intrinsic 2 − 10 keV luminosity (in units of Log(L_2 − 10/erg s⁻¹)); (8) Observed 0.5 − 10 keV flux (in units of Log(F_{0.5 − 10}/erg s⁻¹ cm⁻²)).
