Fig. 9

Influence of the planetesimal belt width, ΔrPB, on a) the SED, b) the 1.3 mm radial profile, c) the V- and H-band profiles, and d) the degree of polarisation. The filled patterns in panel b) depict the location and the radial width of the planetesimal belts (black-hatched 5 au, red-shaded 17 au). The profiles were vertically scaled by 1.7 (ΔrPB = 5 au) and 1.5 (ΔrPB = 17 au) to compensate for the modelling imperfections mentioned in Sect. 4.1.1.
