Density map of extrapolated projected position of PZ Tel B on July 22, 2003, superimposed to the best χ² orbit. Left plot: large scale map showing the data points, the orbit, the predicted position for that orbit on 2016.0, 2018.0, 2010.0 (blue points), and the cloud of positions on July 22, 2003, computed for all solutions out of our posterior sample (shortly after periastron); right plot: enlargement of the periastron region with the cloud of projected positions. The peak of the distribution is indicated with a black star.
