A new catalog of homogenised absorption line indices for Milky Way globular clusters from high-resolution integrated spectroscopy

We perform integrated spectroscopy of 24 Galactic globular clusters. Spectra are observed from one core radius for each cluster with a high wavelength resolution of ~2.0 A FWHM. In combination with two existing data sets from Puzia et al. (2002) and Schiavon et al. (2005), we construct a large database... Show more
