MUSE library of stellar spectra

The dataset comprises a library of 35 high-fidelity MUSE stellar spectra for a subset of the stars part of the X-SHOOTER Spectral Library, covering the Hertzsprung-Russell diagram for both extragalactic and stellar studies. We verified the continuum shape of these spectra with synthetic broad-band colors derived from the spectra. We also report some spectral indices from the Lick system, derived from the new observations. The spectra span the range from ~4800 to ~9300 Angstrom, with a resolving power varying within this limits from 1750 to 3750. The observations were carried out with the MUSE (Multi-Unit Spectroscopic Explorer) integral field unit spectrograph at the VLT in Apr-May 2017 in non-photometric conditions. Each star was observed six times, following the same offset pattern used for MUSE spectrophotometric stan- dards to minimize any systematic effects.
