Gas velocity field superimposed on the gas surface density distribitions in (ThES2)-model 2v (top row), (beta=3)-model 2v (middle row), and (beta=10)-model 2v (bottom row) at two evolutionary times, as indicated in each panel. The red circles outline the radial distance beyond which the azimuthally averaged angular velocity deviates from the Keplerian rotation by more than 10%. The green contours outline the regions where the gas surface density drops to 0.1 g cm⁻¹. The time is counted from the instance of disk formation. The scale bar is in log g cm⁻².
