Comparison of the polarized intensity maps for different grain sizes. All panels are for the well mixed, i.e. flaring, disk models. Upper panels are for the compact grains, lower panels for the fluffy aggregates. The maximum particle size in the size distribution increases from left to right. Spatial scale is in arcseconds. The length of the vectors is proportional to the degree of polarization. The inclination of the disk is 55° with respect to pole on. Color scale is the same as in Fig. 3.
