$^{\star}$ From Dinescu et al. (1999); $^\dagger$ computed using the galactic potential from Paczynski (1990).
Consecutive columns list the cluster NGC number, apogalactic radius $R_{\rm a}$, perigalactic radius $R_{\rm p}$, eccentricity e, orbital period P, circular velocity of the gravitational potential at the distance of apogalacticon  $V_{\rm c,a}$ and destruction rate due to disc shocking  $\nu_{\rm sh}$.
