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.
