Table 2: Distance, colour indices (from SIMBAD and Hipparcos Catalogue, ESA 1997), and effective temperatures (we assumed an uncertainty of 100 K for V-I index). The iron abundances reported in this table (from Method 1) were used to derive the effective temperatures from the B-V colour index (Alonso et al. 1996, 1999).

a: $(V-I)_{\rm c}$ is measured in the Cousins system, to convert it to the Johnson system used by Alonso et al. (1996, 1999) we used the Bessel (1979) transformation: $(V-I)_{\rm J} = (V-I)_{\rm c}/0.778$.
