Table 1: The parameters of the three series of models presented in this paper. p is the power law index for the surface density ( $\Sigma (R) \propto R^p$ ). $M_{{\rm dust,small}}$ is the mass in small (0.1 $\mu$ m) grains. These grains are evenly distributed with the gas in a constant gas-to-dust mass ratio. For the A and B models, this ratio is 100. For the BL models this ratio is 100, 1000, 10 000 etc., but still constant over the disk. The $M_{{\rm dust,big}}$ is the mass in big (2 mm) grains which are assumed to be located in a thin midplane layer. This parameter is only non-zero for the BL series, and it is taken such that $M_{{\rm dust,small}}+M_{{\rm dust,big}}=10^{-3}~M_{\odot}$ . In this way, the BL series simulates a process of converting small grains evenly distributed in the disk into big grains located at the midplane. $M_{{\rm disk}}$ is the total mass of the disk (dust+gas) as calculated from the three disk parameters. It is therefore not a model parameter. Note that the B1 and BL1 models are identical.
