Optical-IR color, R− [4.5] vs. L_{4.5 μm}. X-ray emitting AGNs are plotted with open squares. Top panel shows the corresponding distribution of MIR luminosity in the 4.5 μm for obscured (shade histogram), unobscured (dotted line) AGNs, and X-ray emitting AGNs (dot-long dash histogram). We introduce an artificial shift of 0.02 in the dot-long dash histogram for clarity. Right panel shows the color distribution of both AGN samples (solid line histogram) and the corresponding distribution considering AGN with X-ray emission (dash lines).
