Resulting percentage of polarization, P, as a function of viewing angle, i, for a complex AGN model (see text). The half-opening angle of the equatorial scattering disk is set to 10°. Legend: the different curves denote common half-opening angles of the torus and the polar winds of 30° (red squares), 45° (blue diamonds), and 60° (green triangles with points to the top). The isolated symbols indicate a polarization position angle γ = 90° (parallel), connected symbols stand for γ = 0° (perpendicular). From left to right: increasing the polar outflow optical depth from 0.03 to 1; From top to bottom: increasing the optical depth of the equatorial disk from 0.1 to 5.
