Scientific paper

It is shown that the combination of a UV-sensitive CCD and a well-calibrated photometric system makes it possible to determine metallicity and distance of individual dwarf stars to distances beyond 5 kpc with reasonable accuracy, allowing the chemical composition and density variation of the various populations to be studied. Estimates of (Fe/H) and M(V) are derived for dwarf stars brighter than V roughly 16 m with accuracies of 0.4 dex and 0.5 m, respectively. For stars as faint as V roughly 17 m, the obtained accuracies are 0.6 dex and 0.9 m, respectively.
