Left: top three best-fitting orbits out of 5 × 10⁶ runs of our LSMC fit for a mass of 1.22 M_⊙. Solid lines represent the apparent orbits. Here the red dashed lines represent best-fitting orbits that are not compatible with the disk while the blue lines represent orbits compatible with the disk. Right: same image zoomed-in on the data points. The corresponding orbit elements are listed in Table 6.
