Notes. Elemental abundances used in the dust-depleted inner disk and dusty outer disk in ProDiMo. Solar abundance values are adopted from Asplund et al. (2021) and given in relative abundance: nx/n⟨H⟩. The outer-disk column shows the solar abundance reduced by the elements locked in dust, and the inner-disk column shows the solar abundance for the four species that are affected by dust sublimation.
