Notes. (a) Dust properties are the same as those used in Andrews et al. (2009) and Bruderer et al. (2015). Dust compositionand optical constants are taken from Draine & Lee (1984) and Weingartner & Draine (2001). (b) Only used in the DALI model, not in the viscous disk model. The viscous disk model assumes a geometrically flat disk.
