  We present an improved uvby-metallicity relation calibrated for F, G, and
early K dwarfs, and an analogous uvby-T(eff) relation, both derived using a
Levenberg-Marquardt minimization scheme. Our calibrations are based on 1533
stars which appear in both the Cayrel de Strobel (2001) metallicity
compilation, and in the Hauck-Mermilliod (1998) catalog of uvby photometry. We
also examine the speculative possibility of using uvby photometry to produce a
uvby-planeticity calibration. We conclude that while there is likely no strong
photometric indicator of the presence or absence of short-period planets, the
possibility of a spectroscopic indicator of planeticity is well worth
examining.
