Absorbed X-ray (2–10 keV) X-ray luminosity against the 12 μm luminosity. The large circles correspond to the best candidate Compton-thick sources as suggested by the large equivalent-width FeKα lines. The typical errors are of the order of 30% and 20% for the IR and X-ray luminosity respectively, including the uncertainties in the model fitting. The hatched diagram represents the 1σ envelope of the local (Gandhi et al. 2009) relation. Open circles correspond to X-ray luminosities corrected for absorption (see Table 1). For two sources (PID-222 and PID-324) the absorbed luminosity equals the unabsorbed luminosity. The dotted line corresponds to a factor of 30 lower X-ray luminosity as is typical in many Compton-thick nuclei.
