We collected radial velocities of more than 50.000 individual stars in 156Galactic globular clusters (GGC) and matched them with HST photometry and GaiaDR2 proper motions. This allowed us to derive the GGC's mean proper motions andspace velocities. By fitting a large set of N-body simulations to theirvelocity dispersion and surface density profiles, combined with newmeasurements of their internal radially dependent mass functions, we havedetermined their present-day masses and structural parameters, and for 144 GGCstheir internal kinematics. We also derive the initial cluster masses bycalculating the cluster orbits backwards in time applying suitable recipes toaccount for mass-loss and dynamical friction. The new fundamental parameters ofGGCs are publicly available via an online database, which will regularly beupdated.
