Abstract:

We present a catalogue of published absorption-line Mg₂ indices of galaxies and globular clusters. The catalogue is maintained up-to-date in the HYPERCAT database. The measurements are listed together with the references to the articles where the data were published. A coded description of the observations is provided. The catalogue gathers 3541 measurements for 1491 objects (galaxies or globular clusters) from 55 datasets. Compiled raw data for 1060 galaxies are zero-point corrected and transformed to a homogeneous system.

Key words: galaxies: galaxies: general -- galaxies: star clusters -- galaxies: stellar content
