Notes. We only summarise the properties of those Mg ii absorbers that most likely have an intervening sub-DLA or DLA. Following the typical approach in the literature, we call absorbers with EWrest(Mg ii λ2796) > 1.0 Å strong, with 0.3 Å < EWrest(Mg ii λ2796) < 1.0 Å intermediate and with EWrest(Mg ii λ2796) < 0.3 Å weak systems. Absorbers are marked by † if the doublet is saturated.
Chen et al. (2005) identified two velocity components that are separated by 57 km s-1.
