The Keck/DEIMOS Stellar Archive

This dataset provides radial velocities and equivalent width measurements for individual stars in 78 Milky Way satellite galaxies and globular clusters. The dataset consists of 411 DEIMOS multislit masks taken with the 1200G grating. The catalog data includes 22,339 individual stars, in many cases with multiepoch measurements. The data pipeline and catalog properties are described in detail in Geha et al. 2026. This Contributed Dataset includes access to the reduced 1D spectra and multiepoch measurements.
