Open Cluster Chemical Abundances and Mapping catalog

The Open Cluster Chemical Analysis and Mapping (OCCAM) survey aims to produce a comprehensive, uniform, infrared-based spectroscopic dataset for open clusters. Our analysis combines APOGEE radial velocities and metallicities with proper motion observations from Gaia Data Release 2 to establish membership probabilities for APOGEE stars in open cluster fields. This first VAC from the OCCAM survey considers open clusters with 4 or more APOGEE members and consists of two datasets from Donor et al. (in press): bulk cluster motions (radial velocities, proper motions) and abundances for reliable elements, as well as the membership probabilities for all stars considered in the open cluster analysis.
