Modeling the AGN unified scheme by three reprocessing regions (see text). The fraction F/F_∗ of the central flux is plotted from 2000 to 8000 Å (upper panel) and the spatially integrated polarization P is plotted versus the observer’s inclination i (lower panel). Left column: an AGN model composed of only uniform-density reprocessing regions, while the middle and right columns: different AGNs (with an extended torus in the middle and a compact torus on the right side sustaining the same, θ₀ = 30°, half-opening angle). The clumpy models are composed of the same three reprocessing regions (regarding the smooth-density AGN) which are now fragmented (radiation supported disk: ℱ ~ 0.25, torus: ℱ ~ 0.25, and ionized winds: ℱ ~ 0.06).
