\caption{Proper motion results.
For each model component, we give the number of data points for the fit of the trajectory ($N$),
the mean position angle ($\langle\Theta\rangle$), the mean angular speed $(\langle\dot{\Theta}\rangle)$, the mean proper motion ($\langle\mu\rangle$, and its corresponding $\beta^{\rm{obs}}_{\rm{app}}$$\langle\mu\rangle$), as well as its radial ($\langle\mu_{\rm{rad}}\rangle$) and normal component ($\langle\mu_{\rm{norm}}\rangle$, and its corresponding  $\beta^{\rm{obs}}_{\rm{app\_norm}}$).}
