The columns contain successively McClure et~al. (\cite{mctf}) identification, $V$ and $B-V$, the radial 
velocity ($V_{\rm r}$) and error ($\epsilon$) in km s$^{-1}$, the number of measurements ($N$) from Coravel, 
the data from Minitti (\cite{dm95}), (DM), and Friel \& Janes (\cite{fj93}), (FJ), and remarks on duplicity
and membership.
