Velocity profiles of selected low-ionization transition lines from the DLA system at z_abs = 2.811 towards Q 0528−250. There is a multi-component structure around 200 km s^-1 in this system. However, these components are cleanly observed only in the S ii lines. For important transitions, such as for Zn ii and the other metals, the multi-component decomposition is not statistically significant because of the lower S/N, especially over weak transitions. We therefore adopted a single component to more robustly estimate the total column density of the majority of the metals. Our column density measurements are in good agreement (mostly within 0.05 dex, and within 0.1 dex for Si ii) with the values in the literature (Lu et al. 1996; Centurión et al. 2003); see Sect. 2.2.
