Log() vs. Log (L_{5.8 μm}) for several CT candidates. Grey circles represent literature CT candidate AGN (see Lanzuisi et al. 2015a, for more details). Red diamonds represent our MIRO targets; intrinsic X-ray luminosities of the X-ray detected objects are also indicated with upper bars. The green shaded area is the relation of Lutz et al. (2004) for a sample of low-redshift, unobscured AGN. The orange solid line is the relation for high-redshift unobscured AGN (Fiore et al. 2009), while the dashed and long dashed lines are the expected relation for a 10²³ cm^-2 and 10²⁴ cm^-2 absorber.
