Table 6:

Ionic column densities of oxygen in 10²² m^-2.
X	Mod A $_{\rm sim}$ ^a	Mod A^a	Mod B^b	Mod C^c
O I	3.0	3.1	2.9	2.7
O II, O III, O IV	$\equiv$ 0	$\equiv$ 0	0.35	0.1
O VII, O VIII	$\equiv$ 0	$\equiv$ 0	0.05	0.05
Dust	$\equiv$ 0	$\equiv$ 0	$\equiv$ 0	0.35
Total $N_{\rm O}$	3.0	3.1	3.3	3.2

Notes. ^(a) Mono-phase gas (Table 3 for the simultaneous EPIC-RGS fit). ^(b) Three-phases gas (Table 3). ^(c) Gas + dust model (see Table 4). The agreement between the oxygen column densities estimated with different models validates our method.
