Notes.The last four columns are the results from fitting the depletion sequences following Wiseman et al. (2017b). (a) The molecular fraction is given by f(H2) = 2N(H2)/(2N(H2)+N(H)). (b) The metallicity, [X/H], was determined using the element with the lowest depletion for which a column density could be measured, i.e., in this order: Zn II, S II, or Si II.
