Ensemble of one million orbits for Terzan 2 in the frame corotating with the MW bar, projected on the equatorial (top) and meridional (bottom) Galactic planes in the non-inertial reference frame with a bar pattern speed of 31 (left), 41 (middle) and 51 (right) km s⁻¹ kpc⁻¹, and time-integrated backward over 2 Gyr. The yellow and orange colors correspond to more probable regions of the space, which are most frequently crossed by the simulated orbits. The solid black line shows the orbital path of Terzan 2 from the observables without error bars.
