3. Atmospheric parameters
Effective temperature and surface gravity values for each star have been estimated from and Geneva photometry using the calibrations of Castelli (1991) and Kunzli et al. (1997). The necessary colour indices were taken from the Catalogue of Geneva Photometric System (Rufener F., 1988) and the Catalogue of Data (Hauck & Mermilliod, 1998). Results of the individual determinations together with the finally adopted values of and are presented in Table 2.
