Proper motions of TWA-5 A and B

The diagram shows the relative positions of TWA-5 A and TWA-5 B, as measured on the sky by the HST in 1998 (points 1 and 2) and the VLT in 2000 (3 and 4). The ellipses indicate the measurement uncertainties. It is obvious that the two objects move in nearly the same direction and with the same speed. This greatly strengthens the conclusion that they are physically connected in the same multiple stellar system.
