This is the 4th (Mar. 2023) version of our globular cluster database. The following pages contain information on the fundamental parameters of 168 Galactic globular clusters derived by fitting N-body models to an up-to-date compilation of ground-based radial velocities, Gaia DR3 proper motions and HST based stellar mass functions. Mean cluster motions are based on Gaia EDR3 data (see Vasiliev & Baumgardt (2021) for details on the analysis of the Gaia EDR3 data. This version uses the V-band luminosities derived in Baumgardt et al. (2020) and the cluster 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 Baumgardt et al. (2023). All clusters are fitted with the IMF found in this paper. Finally, the rotation profiles of the clusters were derived in Sollima, Baumgardt & Hilker (2019).
Our globular cluster database consists of three tables, one presenting mean radial velocities, proper motions and orbital parameters for MW globular clusters, one containing the masses and structural parameters for MW globular clusters and one giving radial velocities, proper motions and structural parameters for Local Group star clusters. You can also download the velocity dispersion profiles of MW globular clusters and the individual radial velocities for them.

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