Normalized migration rates of planets with different masses between 0.2 and 2 M_J. The migration rate is scaled with the slow down factor and planet mass (see Eq. (13)). The slope of the black line is 1. The dotted line corresponds to α = 0.001. Accreting planets are indistinguishable from the non-accreting planets and therefore not shown here. Otherwise the plot is similar to Fig. 13.
