Table 1: Data of the sample stars. Visual magnitudes and spectral types are from the SIMBAD database. The effective temperatures ( $T_{\rm eff}$ ), $\log g$ , metallicities and barium abundances are from Zacs (1994) for all stars with the exception of HR 1016 (Pilachowski 1977), HR 4932 (McWilliam 1990), and HR 5058 (Luck & Bond 1991). The colors (V-K) and (R-I) are from Hoffleit & Jaschek (1982) and Johnson (1966). The stars HR 440, HR 1326 and HR 4932 ( $\epsilon$ Vir) are the three normal giants included in the sample.
