Luminosity-redshift plot of the sample. The median of the intrinsic luminosity (logarithmic, in erg / s) and redshift posterior probabilities have been used from the torus+pexmon+scattering model. Sources are classified as Compton-thick (N_H> 10²⁴ cm^-2), obscured (10²² cm^-2<N_H< 10²⁴ cm^-2) or unobscured (N_H< 10²² cm^-2) when the majority of the probability posterior of N_H lies in the respective range. Because of their heavy absorption, the detection of Compton-Thick AGN is biased towards higher luminosities, compared to Compton-thin AGN.
