Resumen:
We present a library of 47 open-cluster integrated spectra, mostly
obtained at CASLEO (San Juan, Argentina) in the range 3600 < λ
< 7400 Å, which are made available at CDS. The data are
combined with previous spectra to obtain 10 high signal-to-noise ratio
basic templates in the young and intermediate-age domains, which are
also provided in the library. These Galactic disc templates represent
the increased time resolution spectral evolution of a stellar population
unit around the Solar metallicity level. The improved signal-to-noise
ratio of the present templates with respect to previous template lists,
together with their increased time resolution, allowed us to improve the
fundamental parameters of some open clusters. The present spectral
library will be useful for several astrophysical applications,
particularly for population syntheses of star-forming giant galaxies.
