Table 2:
Compilation of D/H, D/O, titanium and iron data. Errors bars
are quoted in the usual way with negative errors as indices and
positive errors as exponants. References of TiII data used in the
correlations are: (a) Prochaska et al. (2005), (b) Ellison et al. (2007), (c) this work. Targets in common with Ellison et al. (2007) are marked with an asterix. The column-densities derived by these authors are log (TiII) = 11.10
0.02; 11.31

0.04 for
Vel;

Cen and
Pup respectively and are in
agreement with our determinations within uncertainties.
D, H, D/H, D(Fe) are the values compiled by Linsky et al. (2006),
while D, O, D/O are those compiled by Oliveira et al. (2006). The
three targets with a very high D/O and discussed in Sect. 3.2 are
marked with a #; the first D/O value is the published value used in
Fig. 9a. The second number is the reduced value used in Fig. 9a (see Sect. 3.2).
