Masses and radii as derived in this paper vs. those derived for 1,040 F, G, and K stars by \cite{VF05}. Top panels: Mass and radius as derived directly from the parallax-based luminosity, \(T_{\rm eff}\), and \(\log g\). Bottom panels: Mass and radius as derived from theoretical isochrones and luminosity, \(T_{\rm eff}\), and [Fe/H] as input parameters. Dotted lines in the left-hand panels indicate the approximate mass of an F0 star, the largest to be expected in this sample.
