This release provides stellar spectroscopy of galactic globular clusters in YJ band (1.0-1.35 μm), for a total of 5397 1-D extracted spectra in 30 clusters. The data was acquired using the K-band Multi Object Spectrograph (KMOS) under the ESO large program 193.D-0232, PI F. R. Ferraro.

The targeted stars are mainly cool giants in the brightest portion of the Red Giant Branch selected from suitable Color-Magnitude diagrams. All targets are relatively bright objects, typically with J<14. The spectra have been extracted manually by visually inspecting each IFU and selecting the brightest spaxel corresponding to each target star’s centroid. The aim of the large program is to probe globular cluster internal dynamics by studying the radial velocity dispersions and rotation profiles of a representative sample of galactic globular clusters. Additional information is available in the release description.

Data are available both via ESO Archive Science Portal and programmatically; DOI:  https://doi.eso.org/10.18727/archive/76.
