Example of the velocity profiles of interstellar absorption lines. The line-of-sight shown is that towards HD 147889. From top to bottom the CH⁺ (both at 3957.7 and 4232.5 Å, latter as thick line), CH, CN R(0), Ca i, and K i line (both 7665 and 7699, latter as thick solid line). The strong feature at  ~15 km s^-1 in the bottom panel is a telluric absorption line. Similarly, velocity profiles for all sightlines are included in Appendix D.
