      \caption{\label{tab:prop}Stellar and sightline properties. Distances, reddening and spectral types are from
Diplas \& Savage (\cite{Diplas1994}) unless otherwise noted. The typical uncertainty in the distance
is 30\%. The molecular hydrogen fraction along the sightline toward HD~24534 is from
Rachford et~al. (\cite{Rachford2002}), the other sightlines have been measured by A2003.}               %\centerline
