Table 7:

Inferred metallicity, $N_{\rm HI}$ and D-index of Mg II systems with $W_{\rm r}>1.0$ Å in the UVES sample.
GRB	$z_{\rm abs}$	[X/H]^a	$N_{\rm HI}({\rm cm}^{-2})^a$	D-index^b
021004	1.380	-0.63	20.3	$8.32\pm0.22$
021004	1.603	-0.65	20.8	$9.99\pm0.47$
050820A	0.692			$9.0\pm0.03^c$
050820A	1.429	-0.34	>19.2	$8.13\pm0.22$
060418	0.603	-1.13	>22.0	$10.39\pm0.09^d$
060418	0.656	-0.77	>19.2	$7.51\pm0.05$
060418	1.107	-0.85	21.1	$8.17\pm0.06$
060607A	1.803	-0.21	19.0	$9.12\pm0.06$
080319B	0.715	-0.17	>18.7	$8.06\pm0.01$

^a Metallicities and $N_{\rm HI}$ values inferred using the relation by Ledoux et al. (2006); ^b D-index calculated using Eq. 6, following the method recommended by Ellison et al. (2009); ^c D-index calculated without including the iron column density term (see Ellison et al. 2009); ^d iron lines are saturated. The D-index calculated without including the iron column density term would be $D=9.48\pm0.08$ ;
