Library of Lick/IDS indices for binaries

DOI

Using evolutionary population synthesis, we present 13 refined absorption-line indices defined by the Lick Observatory Image Dissector Scanner (Lick/IDS) system for an extensive set of instantaneous-burst binary stellar populations (BSPs) at high resolution (~0.3{AA}), and 38 indices at intermediate resolution (3{AA}). The ages of the populations are at an interval of 1Gyr in the range 115 Gyr, and the metallicities are in the range 0.004-0.03. These indices are obtained by two methods: (i) using the empirical fitting functions (FFs method); (ii) measured directly from the synthetic spectra (DC method). Together with our previous paper, a data base of Lick/IDS spectral absorption-line indices for BSPs at high and intermediate resolutions is provided. This set of indices includes 21 indices of Worthey et al. (1994, Cat. ), four Balmer indices defined by Worthey & Ottaviani (1997, Cat. ), and 13 indices with the new passband definitions of Trager et al. (1998, Cat. , hereafter T98.
