We present a database of 908 spectra of 709 stars obtained with the
ELODIE spectrograph at the Observatoire de Haute-Provence.
52 orders of the echelle spectra have been carefully fitted together to provide
continuous, high-resolution spectra in the
wavelength range nm. The archive provides a large coverage of the
space of atmospheric parameters:
Teff from 3700 K to 13 600 K,
from 0.03 to 5.86
and [Fe/H] from -2.8 to +0.7.
At the nominal resolution,
, the mean signal-to-noise ratio is
150 per pixel. The spectra given at this resolution are normalized to their
pseudo-continuum and are intended to serve for abundance studies, spectral
classification and tests of stellar atmosphere models.
A lower resolution version of the archive, at
, is calibrated in
physical flux with a broad-band photometric precision of 2.5% and
narrow-band precision of 0.5% . It is well suited to stellar population
synthesis of galaxies and clusters, and to kinematical investigations of
stellar systems.
The archive is distributed in FITS format through the HYPERCAT and CDS databases.
