Dust properties of our best-fit model.
| Grain | Size [μm] | Composition |

| Inner disk and wall (<20 AU) | 0.4 | ISM† |
Notes. Opacities are calculated assuming a grain size distribution f(a) ∝ a-3.5 with typical size a with a width of 0.25 dex.
Composition of ISM: 13.8% MgFeSiO4, 42.9% MgSiO3, 38.3% Mg2SiO4, 1.8% NaAlSi2O6, 5% C, Solar: 12% MgFeSiO4, 12% MgFeSi2O6, 12% Mg2SiO4, 12% MgSi2O6, 15% FeS, 40% C.
