{\small $m$ is the mass in sub-$\mu$m-sized dust grains, $p$ is the power which governs the decline of the surface density with increasing distance to the star ($\Sigma \propto R^{-p}$), $i$ is the inclination of the disk with respect to the line-of-sight, $\Phi$ is the artificial scaling factor for the inner disk scale height, with $\Phi = 1$ indicating hydrostatic-equilibrium models. See text for details.}
