Notes. GIRAFFE was upgraded in February 2015, resulting in an improved resolving power. All our HR04 observations are from 2016 onwards. The number of spectra listed is the number of individual spectra from each setup, the number of spectra when combined per night (nightly) and the number of spectra when combined over all nights (stars). The numbers include science cluster, archive science, and archive calibration open cluster stars, but not benchmark stars.
