Description
This is a compilation of spectra collected along the years at ESO, OHP, CFHT and CASLEO in the near-ultraviolet, optical and near-infrared ranges, complemented by IUE observations. Aiming at population synthesis techniques, average template spectra were built from weighted sums of individual spectra of star clusters taking into account their spectral similarities, ages and metallicities. Morphological types and spectral types, beyond spectral similarities, were considered respectively for galaxy and star template building. Both template and individual spectra are included in the library, which contains spectra for 243 galaxies, 190 clusters and 72 stars, amounting 868 spectra in the various spectral ranges.
