Angular momentum deposition ∂F_dep/∂R for our fiducial 2D and 3D models (dashed and solid lines, respectively) and for four different equations of state. Models with cooling (β, radiative) have β^2D ≈ 2. As in Fig. 1, faded and saturated colors indicate raw and smoothed data, respectively, showing that our smoothing procedure has negligible effects beyond the corotating region. The bottom panel compares the four equations of state for our 3D models, highlighting the role of cooling.
