Table 1: Stellar and sightline properties. Distances, reddening and spectral types are from Diplas & Savage (1994) 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. (2002), the other sightlines have been measured by A2003.
