The X-ray (2–10 keV) luminosity (uncorrected for absorption) as a function of the torus 6 μm luminosity. Filled (black) circles represent the AGN while open (green) circles denote the candidate galaxies. Only nine AGN are plotted, because source W-92 has no torus contribution. The solid lines denote the region occupied by unabsorbed AGN, while the region beyond the short-dashed line is populated by Compton-thick AGN in the local Universe (adapted from Alexander et al. 2008). For comparison we plot the positions of Arp 220 and the Compton-thick AGN Mrk231 in the diagram.
