Orbits of the 10 selected GCs in the Sormani et al. (2022) potential rotating with a constant pattern speed of Ωb = 35 km s−1 kpc−1. The frame shown is corotating with the bar (gray ellipse), and the current positions of the Sun and the GCs are shown with the ⊙ and red points, respectively. In all, 6 of the 10 GCs (e.g., 47 Tuc) orbit close to the CR, since they remain on one side of the bar.
