Remarks: PA is from north over east to south, after correcting for the detector orientation.\
(a) Absolute errors, (b) relative errors, (c) no relative errors available, because another astrometric calibration binary was observed, (d) significance in Gaussian $\sigma$ against background (b/g) hypothesis for each epoch compared to the first new epoch (2005.4) regarding (re) PA (Fig. 1) and separation (Fig. 2); the background hypothesis is that the companion is a non-moving background object, in which case GQ Lup A would move away due to its known proper motion. The significances compared from the three earlier observations from 1994 to 2002 are 5.4,
