VizieR Online Data Catalog Classification of stellar spectra 644-681nm (Damiani+, 2014)

A set of newly-defined spectral indices is presented for all stars in the field of the gamma Vel cluster, observed within the Gaia-ESO Survey. All indices are based exclusively on the spectral range 6440-6810 Angstroms, corresponding to the VLT/FLAMES Giraffe setup HR15N. Fundamental stellar parameters can be derived from these indices as explained in the paper. Stars with either high cluster membership probability, or/and SB2 binaries, are flagged. (2 data files).
