TransitionRatio
This parameter is specific to a set
of simulations performed to evaluate the efficiency of planet trapping
at a disk temperature transition. Unless you want to reproduce these
very specific simulations, you
should simply ignore this variable. If you use it, you also have to
define TransitionRadius and TransitionWidth.
TransitionRatio
is the thickness ratio of the outer to the inner disk. Beyond the
transition (r > TransitionRadius),
the thickness profile is whatever is given by AspectRatio, while before the transition
it corresponds to this profile multiplied by TransitionRatio. Note that the FlaringIndex parameter should be set to 0
when defining a temperature transition.
