Effects of dust on ideal galaxy models; Each row shows a model of different dust properties, from top to bottom they are defined by (h_z,dust,h_r,dust) = (0.1, 0.5) (0.4, 0.5), (0.1, 2.), and (0.4, 2.). Left column: vertical profiles at different radial positions (as given in the legend in terms of stellar scale length); middle column: radial profile at different heights above the plane (see legend, given in stellar scale heights); right column: face-on view of the position where the optical depth reaches one (τ = 1) for different heights above the plane (see legend, given in stellar scale heights); the dashed lines are circles of one, two, and three scale lengths of the stellar component.
