Family of orbits that fit all our PIONIER data points. The left panel shows the observed points and the projected orbits, as well as 1σ ellipses allowing to distinguish between the various orbits. A large number of orbits still fit the data, with the longer orbits being the more eccentric. The right panel shows the de-projected orbits, in absolute scale, assuming a distance of 5.4 kpc. All orbits from Fig. 6 are shown here.
