Comparison of the metallicities and Δv₉₀ values of ESDLAs (blue circles) and GRB-DLAs (red squares) observed with X-shooter. For comparison, the grey points show the values for the overall intervening QSO-DLA population from Ledoux et al. (2006). The histograms in the top panel provide the Δv₉₀ distributions of the two samples using the same colour-coding as in Fig. 8.
