All Tables

Table 1: Spectral type, visual apparent magnitudes, colour indices, number of exposures ( N), and mean resulting signal-to-noise ratios (at $\lambda \approx$ 6000 Å) for the program stars. The spectral types, magnitudes and colour indices are from the SIMBAD database.
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).
Table 3: Abundance results for the subgiant stars. Number of transitions used to derive the abundances of the different elements ( N), mean values ( $\langle\rangle$ ) and error bars, corresponding to 1 $\sigma$ of the atmospheric parameters and abundances, as determined from Methods 1, 2 and 3. The notation is the usual one: $[A/B]=\log [A/B]_{\star}-\log [A/B]_{\odot}$ .
Table 4: Mean values of the derived atmospheric parameters and abundances for the dwarf stars as determined from Methods 1 and 2 ( $\langle\rangle$ ). Blanks indicate that the equivalent widths could not be reliably measured.
Table 5: Kinematic data and age determinations ( $\tau _{\rm iso}$ ). The top half of the table contains information about coordinates (from the Hipparcos Catalogue, ESA 1997), and radial velocities of the program stars (from the SIMBAD database). All coordinates used are for equinox 1950. The lower section shows the velocity data obtained, along with evolutionary ages. The last row gives the stellar mass derived from the evolutionary tracks (Method 1).
Table 6: Wavelengths, excitation potentials and log gf values from Morel et al. (2003), and equivalent widths measured in the program stars.
