Relative astrometry for the point source detected in RU Lup, at three different epochs, from bottom to top: 2016 March, 2017 March, and 2019 May. The predicted motion of a comoving object follows the black line, with the red circles being the expected astrometry of a comoving object at the different epochs of the observations. Blue circles are the real astrometry of the observed point source at the different epochs of the observations.
