Table 1: Description of the sample. The neutral and molecular hydrogen column densities were taken from Ledoux et al. (2003). Both [Fe/H] and metallicity values were from this work and correspond to the values integrated over the systems. Metallicity was derived in all cases from [S/H], except for Q 1157+014 for which [S/H] determination was uncertain, so we used [Zn/H] instead.
Table 2: Atomic data.
Table 3: Solar abundances and typical galactic depletion values ofelements investigated in this paper.
Table 4: Total column densities and integrated abundance ratios relative to solar in the six DLAs of our sample.
Table 5: This table summarizes the abundance ratios for the six systems studied. Each system was decomposed in different sub-clumps. For each range of velocities, we determined the mean value of the [X/S] ratio, its error $\sigma =\sqrt {\sum _{i=1}^{n}\sigma ^2_{i}/n}$ , as well as the standard deviation around the mean (in italics), as an indicator of the inhomogeneity through the subclump. The molecular components were isolated and their depletion values marked in bold face.
