Fig. 5
Relative astrometry of the point source labeled “bkgd star” in Fig. 3 (colored data points with thick error bars) measured in SPHERE data (epoch 2015.37) and archival HST/STIS data (epoch 2001.27). The black cross represents the locations assuming that the point source is a stationary background object and accounting for the uncertainties in the proper motion and the distance of SAO 206462.
