Caption: Figure 3.

Top: radial profile of the retrograde orbit fraction from the best-fit Schwarzschild model using the high-resolution orbit library (100,000 orbits). The vertical dashed line at 0﹩\mathop{.}\limits^{\unicode{x02033}}﹩25 ≃ 20 pc marks the boundary of the eccentric-disk region highlighted by the white rectangle in Figure 2. Bottom: distribution of orbits in phase space, showing the mean radius versus orbital circularity. The size of each circular marker scales with the relative weight of the corresponding orbit.
