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 TransitionRatio 
. TransitionWidth is the radial distance 
, expressed in disk pressure scale heights
, over which the temperature transition occurs. More precisely, the logarithm of the disk aspect ratio 
is an affine function of 
between 
and 
.
