Orbit of the stream shown in galactocentric Cartesian coordinates, evolved for 10 Gyr forward in time in the Stäckel axisymmetric Milky Way-like potential. Top: orbit in coordinates aligned with the host galaxy (e.g., plane of the disc is z = 0). Bottom: coordinates aligned with the initial angular momentum vector of the orbit. The bottom right panel highlights the precession of the orbital plane, which is indicative of the non-spherical nature of the potential considered.
