Fundamental parameters of Galactic globular clusters (Nov. 2018 version)

The following pages contain information on the fundamental parameters of Galactic globular clusters derived by fitting N-body models to ground-based based radial velocities, Gaia DR2 proper motions and HST based stellar mass functions. The details of the N-body models can be found in Baumgardt (2017), and Baumgardt & Hilker, (2018). Details on the stellar mass functions can be found in Sollima & Baumgardt (2017). Finally, the analysis of the Gaia data is described in Baumgardt, Hilker, Sollima & Bellini (2019).
