Top panels: vector point diagrams of displacement of all stars within 35 arcsec of the cluster center (left) and spectroscopically confirmed cluster members (right) in units of ISAAC pixels (185 mas/pixel) after 5 years. Bottom panels: a zoom of the central 2  ×  2 pixel vector point area. The most probable cluster members are within the red circle with 0.25 pixels radius (left). They are marked with red crosses on the color−magnitude diagram of this zoomed area (right). All plots show only stars with root-mean-square positions  <0.08 pixels in each coordinate, the Objs 18, 19 and 20 are also labeled.
