\caption{
Parameters of the models used to study the evolution of
a planetary system under the action of an outer disk.
Given are a model name, the used thermodynamics (TD), 
isothermal (iso) or radiative (rad),
the type of outer boundary condition (obc)
(open or closed),  the mass-ratio of the inner planet ($q_1$),
the mass ratio or evolution of the outer planet ($q_2$), the figure
in which the model is displayed.
%%  WK: Edited
The displayed radiative models include heating and cooling only
as the inclusion of the diffusion does not change results significantly.}
