Trajectory followed by the jet for γ_j = 1.2 (solid purple line) and 3 (solid green line). The projections in the orbital plane are also shown with dashed lines. The jet length is 50a, and the counter-jet is symmetric to it with respect to the xy-plane (not shown). The blue circle at the origin of coordinates represents the star (to scale). The jets are plotted starting from the corresponding recollimation shocks.
