Top 3 best-fitting orbits out of 5 000 000 runs of our LSMC fit of the PZ Tel B astrometric data. Solid lines represent the apparent orbits. The right panel is zoomed in on the data points. The corresponding orbit elements are listed in Table 13. We show the data points taken with VLT/NaCo as given in Ginski et al. (2014; blue crosses), as well as the data points taken with Gemini/NICI given in Biller et al. (2013; empty green boxes), together with our SPHERE/IRDIS measurements (red circles). For the orbit fitting, only the VLT/NaCo and SPHERE/IRDIS data points were considered.
