Abstract:
Calibrations are presented here for metallicity ([Fe/H]) in terms of
the ultraviolet excess, [Δ(U-B) at B-V=0.6, hereafter D0.6], and
also for the absolute visual magnitude (MV) and its difference with
respect to the Hyades (ΔMHV) in terms of D0.6 and (B-V),
making use of high-resolution spectroscopic abundances from the
literature and Hipparcos parallaxes.
Description:
UBV photometry [V, (B-V), (U-B)] has been collected from large data
bases in conjunction with the derivation of intrinsic-colour,
metallicity and absolute magnitude calibrations of F-, G- and
early-K-type stars for uvby-beta photometry being derived by
Karata & Schuster (in preparation).
