Plots ot the orbit of Table 3 with their orientation with respect to the line of sight. The larger orbit is the best LSLM χ² model and the smaller one is an example of the highly probable orbit obtained with the MCMC approach. In each case, the dashed line shows the location of the periastron. The position of the planet at different observation epochs is shown as black dots along the orbit (projected error bars in the astrometric measurements are smaller than the symbol size), and predictions for the upcoming years are shown in gray.
