Hard X-ray bolometric correction against the intrinsic 2–10 keV luminosity for 240 type-2 AGN with AGN best-fit (red data). The crosses represent the bolometric correction for 306 type-1 AGN, computed with the approach described in Sect. 6. The green and blue lines represent the bolometric correction and the 1σ dispersion obtained by Hopkins et al. (2007) and Marconi et al. (2004), respectively. The red points and open squares represent the 111 type-2 AGN with N_H from spectral analyses and the 144 type-2 AGN with N_H from HR, respectively.
