Normalized gas‐phase abundances of several ionic species associated with gas in the LLIV Arch at −55 km s﹩^{-1}﹩. Gas‐phase abundances are referenced to H I (filled circles) and ﹩\mathrm{H}\,\,{}^{{\rm{\small I}}}+\mathrm{H}\,\,{}^{{\rm{\small II}}}﹩ (open squares); they are listed in Table 6. The elements are sorted by their condensation temperature (increasing from left to right; see Savage & Sembach 1996).
