Notes. (∗) Column density computed from the measured equivalent width via the measured cross sections given by Campbell et al. (2016). (∗∗) Hydrogen column density, N(H) = N(Hi + 2 N(H2), from direct measurements (HD 169454: Diplas & Savage 1994) or visual extinction, AV (other sightlines; see text for details).
