All Tables

Table 1: Data for the quasars of the absorption sample and measurements of the deviations from the mean color $\Delta (r-z)$ and $\Delta (g-z)$ . Measurements in the (g-z) color index are only given for quasars with $z_{\rm e} \leq 3.4$ (see Sect. 3.2.2). The first 20 DLA-quasars are shown. The full table is available in electronic form at the CDS (see also web page http://adlibitum.oats.inaf.it/vladilo/tables.html).
Table 2: Pool of control quasars used in the present investigation (see Sect. 2). The first 20 quasars are shown. The full table is available in electronic form at the CDS (see also http://adlibitum.oats.inaf.it/vladilo/tables.html).
Table 3: Mean reddening in the observer's frame, $\langle E \rangle$ , and mean extinction in the rest frame, $\langle A_{\rm V} \rangle$ , for different colors and DLA/QSO samples.
Table 4: Mean reddening of sub-samples with different strengths of the Si II 1526 line detected at the redshift of the DLA system.
Table 5: Mean metallicity and extinction per unit metal column density for the DLA-QSOs with Si II measurements.
