The Observatory of Lyon is host to the Centre for Astronomical Reseach of Lyon (CRAL) is a Joined Research Unit (UMR 5574) of the University of Lyon 1 (UCBL), Ecole Normale Supérieure de Lyon (ENS-L), and Centre National de la Recherche Scientifique (CNRS). Projects include ELP-OA, HORIZON, NIRSpec for the James Webb Space Telescope, the Multi Unit Spectroscopic Explorer (MUSE), and the spectrum interpolater for the ELOIDE Library.
The ELODIE interpolator is a service buil on top of the ELODIE library to generate a spectrum given the atmospheric parameters: Teff, log(g) and [Fe/H]. The typical usage of this function is to generate a grid of atmospheric spectra for a set of parameters in order to feed a population synthesis program. The grid used for the PEGASE.HR program has been generated with this method. The program is based on a method described in Prugniel & Soubiran (2001) and uses the version of the stellar library presented in Prugniel & Soubiran (2004). The service responds to the metadata and data requests defined in VOspec for theoretical spectra access (called TSA). A normal SSA positional search will return an empty result.
