VizieR Online Data Catalog: Star cluster Gaia 1 stars equivalent widths (Koch+, 2018)

Observations of four candidate members were taken during four nights in March 2017 using the Echelle spectrograph at the 2.5-m du Pont telescope at the Las Campanas Observatory, Chile, with a seeing of 0.7"-1.0" throughout the nights. Our spectroscopic set-up included a 1.0" slit with 2x1 binning in spectral and spatial dimensions, resulting in a resolving power of R~25000.
