\caption{Cluster membership of program stars from the literature according 
to astrometric, photometric, and spectral type criteria, and ours based on
spectrophotometric parallaxes and radial velocities.  The last column
gives our final membership status obtained by merging the results of the
various criteria. {\it S73} = Sanders (\cite{sanders}), {\it D02} = Dias et~al. (\cite{dias}), {\it C77} = Crawford et~al. (\cite{crawford}),~{\it J83} = Joshi et~al. (\cite{joshi}), {\it W00}~= Wang \& Hu (\cite{wang}).}
