Table 4:

Table of the contributions to the oxygen column-density.
Phase	Constituent	$N_{\rm O}~(10^{22}$ m^-2)	% of $N_{\rm O}^{p}$ ^a	% of $N_{\rm O}$ ^b
Gas	O I	$2.7 \pm 0.1$	$94 \pm 4$
	O II, O III, O IV	$0.10 \pm 0.05$	$4 \pm 2$	$90 \pm 6$
	O VII, O VIII	$0.05 \pm 0.01$	$2.0 \pm 0.5$
Dust	Silicates	$0.25 \pm 0.05$	85-100	$10\pm 2$
Dust	Aluminates	<0.04	0-15	$10\pm 2$
Molecules	H₂O ice	<0.07	$\sim$ 65	0-2
Molecules	CO	<0.04	$\sim$ 35	0-2

Notes. ^(a) % of $N_{\rm O}^{p}$ represents the contribution of each constituent to the respective phase. ^(b) % of $N_{\rm O}$ give the contribution of the different phases to the total oxygen column density. See also Sect. 3.2.3 and Fig. 11 for the transmission of the main compounds.
