x-y, z-y and x-z projections of Fornax-like O1 (upper panels) and O2 (lower panels) orbits of a point-like mass in the J95 potential (solid lines), and of the trajectories of the satellite’s centre in the corresponding S1 and S2 simulations (yellow and red dots, respectively). The phase-space coordinates of the initial conditions (blue squares) are given in Table 2. The green crosses indicate the observationally determined present-day position of Fornax, which coincides, by construction, with the end point of the reference point-mass orbits. The purple pentagons mark the present-day position of the centre of the satellite in the N-body simulations.
