Lyman series absorption in the ﹩z\simeq 2.536﹩ LLS toward HS 0105+1619. The velocities shown are relative to the H I redshift of ﹩z=2.535998﹩. The vertical scales are linear flux, from zero, and the lower traces are the 1 σ error. The D I absorption is seen at −82 km s⁻¹ in Lyβ, Lyγ, Ly5, Ly6, and Ly7.
