Notes. Column (1): source name; Column (2): selected component with respect to the reference component used for proper-motion measurement; Column (3): radial proper motion; positive values refer to the components moving away from each other; Column (4): apparent radial separation speed measured in the units of c in the source rest frame; Column (5): position-angle change, measured from north to east; Column (6): kinematical age of the component. If a component has negative or negligible proper motion, we used 1-σ of the separation velocity to derive a lower limit (see An et al. 2012). The fit proper-motion plots are shown in Fig. S6.
