B-band surface brightness maps (color scale) overlaid with linear polarization maps (line segments) for inclinations of 20° (left), 75° (middle), and 90° (right column). The top row shows a model with only a stellar bulge, the middle row a model with only a stellar disk, and the bottom row a model with both stellar bulge and disk with a ratio of bulge to total luminosity of B/T = 0.5. The dust disk is the same in the three cases and has a central face-on V-band optical depth of 10.
