APOGEE Globular Cluster members catalog

The SDSS/APOGEE value added catalog of Galactic Globular Cluster stars contains membership information for 7,732 observations (6,422 unique stars) in 72 globular clusters in the Milky Way, derived from DR17. The catalog also contains full information derived from the APOGEE ASPCAP catalog, such as radial velocities and abundances for up to 20 elements.

This value added catalog contains two files: the main catalogue, GC_members, contains DR17 ASPCAP allStar information, plus deviations from mean cluster values, distance from cluster centre, membership probabilities and flags. The GC_parameters catalogue lists global parameters of the globular clusters themselves.

The catalog is described in full detail in Schiavon et al. 2023.
