In Table 2 of Ellison & Lopez (2001) the value of [Si/H] in DLA A should be -1.04. Although the subsequent [Si/Fe] is typical of other DLAs, a low ratio of α/Fe is still supported by [S/Fe], compared with other systems in the literature. The moderate [Si/Fe] ratio could therefore be due to a modest amount of dust depletion, as supported by [Zn/Cr] = 0.18. If dust is present, this would further decrease the already low [S/Fe] in DLA A. Therefore, despite the revised value of [Si/Fe] in DLA A, these results are still supportive of low α/Fe in this double DLA.
