Notes. Fixed parameters are indicated by a dagger (†). The surface density profile is defined as Σ(r) ∝ r− p and scaled to the total disk mass. The location of the gap edge is approximate due to its smooth nature; displayed here is the peak of the radial intensity (Fig. 5). Opacities are calculated assuming a grain size distribution f(a) ∝ a-3.5. Solar composition: 12% MgFeSiO4, 12% MgFeSi2O6, 12% Mg2SiO4, 12% MgSi2O6, 15% FeS, and 40% C. Optical constants are from: silicates (Dorschner et al. 1995; Henning & Stognienko 1996; Mutschke et al. 1998), carbon (Preibisch et al. 1993), troilite (Begemann et al. 1994).
