This is the 3rd (May 2021) version of our globular cluster database. The following pages contain information on the fundamental parameters of 162 Galactic globular clusters derived by fitting N-body models to an up-to-date compilation of ground-based radial velocities, Gaia EDR3 proper motions and HST based stellar mass functions. We have updated our first version (accessible here) with more radial velocities and replaced the Gaia DR2 proper motions by Gaia EDR3 ones (see Vasiliev & Baumgardt (2021) for details on the analysis of the Gaia EDR3 data. This version also contains new V-band luminosities derived in Baumgardt et al. (2020) and uses the new distances derived in Baumgardt & Vasiliev (2021). 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 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.
