Fig. 13

Comparison between a radial (solid dashed line) and vertical (solid plain line) dust stratification in a clumpy equatorial flared disk with spheres of constant radius. The variation of the dust density is linear and decreases from the center of the model (first case) and from the equatorial plane (second case). The top panel shows the normalized photon flux at 1 μm, the second panel is the polarization degree, the third panel is the polarization position angle, and the last panel is the time lag as a function of the system inclination.
