$f_{\rm b}$ marks stars suspected to be binaries. $f_{\rm c} = 1$ identifies Hyades and Coma stars with photometry as given in GCS~I; $f_{\rm c} = 2$ identifies Hyades/Coma stars for which the standard photometry  by Crawford \& Perry (\cite{crawfordPerry}) and Crawford \& Barnes  (\cite{crawfordBarnes}) is used in GCS~II and here. $\pi$ and  $\sigma_{\pi}$ are the new Hipparcos parallaxes and their errors (van~Leeuwen  \cite{vanleeuwen07}), and $\rm Age_{\rm low}$ and $\rm Age_{\rm up}$ are the lower and upper 1-$\sigma$ confidence limits on the computed age. (The full table is only available in electronic form at the CDS).
