Alpha-viscosity parameter as a function of the radial coordinate for a flat and a flared disk, with α_back = 10^-3, α_dz = 10^-5, R_{in - dz} = 2.7 au and R_{out - dz} = 20 au. We consider a disk of 0.05 M_⊙, and for both disk c_{in - dz} = c_{out - dz} = 1. For a flat disk, H_g(R_{in - dz}) = 0.135 au and H_g(R_{out - dz}) = 1 au, while for a flared disk H_g(R_{in - dz}) = 0.165 au and H_g(R_{out - dz}) = 2.013 au.
