47 Tuc in Rubin Data Preview 1: Exploring Early LSST Data and Science Potential

This catalog lists 3,576 probable member stars of the globular cluster 47 Tuc, selected from Rubin Observatory Data Preview 1. Membership was determined through a sequential filtering process combining isochrone-based pre-selection, Gaia proper-motion refinement to exclude SMC and foreground contaminants, and color–color diagram filtering to remove faint background galaxies. This catalog contains only the unique objectId identifiers of the final cleaned sample, intended for cross-matching with the DP1 Object table available through the Rubin Science Platform. This catalog is a product of the results presented in the paper '47 Tuc in Rubin Data Preview 1: Exploring Early LSST Data and Science Potential', submitted to ApJ.
