References: the H₂ fractions are from Cui et al. (2005), Noterdaeme et al. (2008) and Srianand et al. (2012), while the log[l_c] values are from Wolfe et al. (2008a). References for the metallicities, H i column densities and spin temperatures are given in Table 4. Note that PDLAs (e.g. the z = 2.8111 system towards 0528−250) have not been included in the table.
