On-line determination of stellar atmospheric parameters Teff, log g, [Fe/H] from ELODIE echelle spectra. II - The library of F5 to K7 stars

摘要: A library of 211 echelle spectra taken with ELODIE at the Observatoire de Haute-Provence is presented. It provides a set spectroscopic standards covering full range gravities and metallicities in effective temperature interval [4000 K, 6300 K]. The are straightened, wavelength calibrated, cleaned cosmic ray hits, bad pixels telluric lines. They cover spectral [440 nm, 680 nm] an instrumental resolution 42000. For each star, basic data were compiled from Hipparcos catalogue Input Catalogue. Radial velocities precision better than 100 m/s given. Atmospheric parameters (Teff, log g, [Fe/H]) literature discussed. Because scattered determinations bibliography, even for most well-known stars, these adjusted by iterative process which takes account common or different features between standards, using our homogeneous spectra. Revised values proposed. still consistent literature, also lead to self-consistency library, sense that similar have atmospheric parameters. This adjustment was performed step method based on least square comparison carefully prepared spectra, originally developed on-line estimation faint field stars (companion paper main journal). corresponding will only be available electronic form CDS (ftp cdsarc.u-strasbg.fr this http URL).
