Notes. Edge-on, type-2 AGNs have an inclination i = 70 degrees and are face-on, while type-1 AGNs have i = 30°. The extinction in polar direction, E(B − V), included in the AGN module, accounts for the possible extinction in type-1 AGNs, due to polar dust. The AGN fraction is measured as the AGN emission relative to IR luminosity (1–1000 μm).
