Fraction of absorbed sources (at ≥1σ) for IR power-law and IR non-power-law galaxies as a function of the rest-frame absorption corrected 2–10 keV luminosity. The open squares and star symbols show the fraction of absorbed sources taking into account the probability density function for of each individual source for IR power-law and IR non-power-law, respectively (see Sect. 5). Note that these fractions refer exclusively to our sample and not to the overall AGN population.
