Selection of absorption lines in the VLT-UVES spectrum. The median model (black line) and 1σ uncertainties (gray region) from the MCMC fitting routine as well as individual metal lines are shown. The vertical (gray) dashed lines mark the six velocity components of the C I, Zn II, and Ni II metal lines. The yellow lines in the top two panels are absorption features due to higher redshift intervening H I systems. The velocity offsets for Mg I and Cr II are 50 and −63 km s⁻¹, respectively. Note the lack of C I absorption in the strongest Zn II and Ni II component at v ≈ 3 km s⁻¹.
