Notes. 

(a)

Representative values of Galactic depletions in warm-halo gas (WH), warm-disk gas (WD), and cool-disk gas (CD), calculated from Eq. (10) of Jenkins (2009) with F∗ =  −0.28, 0.12, and 0.90, respectively (see Fig. 19 and Table 4 in that paper).

(b)

 ⟨ δX ⟩ : mean value of the depletions of the DLA systems of the merged sample; σX: standard deviation; SEM: standard error of the mean; δX,med: median value of the depletions of the merged sample.

(c)

Same as in note b, but with the inclusion in the analysis of the DLA system at zabs = 1.6265 in QSO 0142-100.
