Notes.

^(a)

Galactic column density provided by the nh tool, using the HI map by Dickey & Lockman (1990).

^(b)

Source intrinsic column density.

^(c)

Fraction of the scattered component relative to the intrinsic power law.

^(d)

Centroid energy and equivalent width respect to the whole continuum of the Fe fluorescence Kα line at the rest frame of the source redshift.

^(e)

The relative strength of the reflection component to the transmitted one, defined as R = Ω/2π, where Ω is the solid angle of the reflector viewed from the nucleus.

^(f)

Normalization factor of the BAT flux respect to the XIS detection.
