Notes. Fitted proper motion of the detected star, from both imaging and model fitting results. Here, P1 and P2 stand for the two different polarization from the GRAVITY data. All the units for proper motion and uncertainties are in mas yr−1. The bottom row includes also the positions of the tentative detection from the 2018 data (Sect. 4.7).
