Abstract:
    We present precise effective temperatures (Teff) of 215 FGK giants
    determined using the method of line-depth ratios. For each star, we
    have measured the line depths and equivalent widths of a large number
    of spectral lines of low and high excitation potentials and
    established ∼100 relations between Teff and their ratios. Starting
    with an initial value Teff, the relations are then self-calibrated by
    an iterative process. Our final estimates have been compared with very
    accurate (1 per cent) published temperatures and show a good
    agreement. Using our calibrations, we derive precise temperatures for
    215 giants with near-solar metallicity, from high-resolution (R=42000)
    and high signal-to-noise ratio (S/N=100250) echelle spectra, obtained
    with the ELODIE spectrometer at the Observatoire de Haute Provence
    (OHP).

Description:
    The investigated spectra were obtained with the 193-cm telescope
    equipped with the ELODIE spectrometer (R=42000).
