Toppanels: reflex proper motions of individual galaxies in mas yr⁻¹ as a function of the distance in arcmin to the center of 47 Tuc. The red solid line marks the running mean of the distribution. The left-hand panel shows the proper motion in the RA direction, whereas the right-hand panel is for the Dec direction. Bottom panels: same as the top panels but now for the proper motions of the cluster stars.
