Abstract:
    A new metallicity distribution and an age-metallicity relation are
    presented for 437 nearby F and G turn-off and sub-giant stars 
    selected from radial velocity data of Nidever et al. (2002, Cat.
    J/ApJS/141/503). Photometric metallicities are derived from
    uvby-Hβ photometry, and the stellar ages from the isochrones of
    Bergbusch & VandenBerg (2001ApJ...556..322B) as transformed to uvby
    photometry using the methods of Clem et al. (2004, Cat. J/AJ/127/1227).
