Notes.

^(a)

The different photo-ionized xabs components.

^(b)

Both the velocity dispersion σ_v and v_C iv are in units of km s^-1. The v_C iv are fixed.

^(c)

The hydrogen column densities N_H are in 10²³ m^-2 units.

^(d)

The ionization parameter ξ = L/n_Hr² is in units of 10^-9 W m.

^(e)

α_SED is the best fitting slope for the PL SED (see also Sect. 4.1.3).

^(f)

PL refers to the fit assuming a power-law SED, LE refers to the Local Emissivity SED including galaxies and QSOs.
