This is the 2nd (Jan. 2020) version of our globular cluster database. The following pages contain information on the fundamental parameters of 159 Galactic globular clusters derived by fitting N-body models to an up-to-date compilation of ground-based radial velocities, Gaia DR2 proper motions and HST based stellar mass functions. We have updated our previous version (accessible here) with the radial velocities of the WAGGS survey (Dalgleish et al. 2020) and archival AAT data. 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). The analysis of the Gaia data is described in Baumgardt, Hilker, Sollima & Bellini (2019). Finally, the rotation profiles of the clusters were derived in Sollima, Baumgardt & Hilker (2019).
Our globular cluster database consists of two main tables, one presenting mean radial velocities, proper motions and orbital parameters, and the other containing the masses and structural parameters. You can also download the velocity dispersion profiles of globular clusters and the individual radial velocities.

The individual GC images are from the Digitized Sky Survey and show roughly 10' x 10' fields centered on the clusters. Click here for the DSS copyright information.
