α profiles averaged over 100 orbits after the fronts have reached their final position (α values are listed on the left axis). Left panel: σ_hot simulation which T_MRI = 0.46. Middle and right panels: σ_cold simulation which T_MRI = 0.1 and T_MRI = 0.13 respectively. The black plain lines remind the temperature profiles from ideal cases. Black dashed lines show the threshold value T_MRI and 5/4T_MRI. The temperature values are listed on the right axis.
