Line depth ratios measured on high resolution (R= 42 000), high S=N echelle spectra are used for the determination of precise eective temperatures of 181 F, G, K Main Sequence stars with about solar metallicity ( 0:5< (Fe=H)<+0:5). A set of 105 relations is obtained which rely Te on ratios of the strengths of lines with high and low excitation potentials, calibrated against previously published precise (one per cent) temperature estimates. The application range of the calibrations is 4000- 6150… CONTINUE READING
