Metallicity vs velocity extent of the low-ionisation metal lines for our sample of proximate H2 systems and a sample of intervening DLAs (mostly from Ledoux et al. 2006 with some additions by Noterdaeme et al. 2008). The green line shows the best-fit relation for high-z intervening DLAs by Ledoux et al. (2006).
