Fraction of the obscured sources (NH > 1022 cm−2) as a function of the intrinsic 2–10 keV luminosity (blue-square points) and the 12 micron luminosity (orange-circle points). The error in the estimated fraction corresponds to the 68 per cent confidence level while the uncertainty in the luminosity axis denotes the range of each luminosity bin used.
