Different ionisation metal lines (Mg II, Fe II, Ar I, O I O I^*, N I, S II, Si II, and Mn II) associated with the z_abs = 2.230 ESDLA system towards QSO SDSS J2232+1242. The plots show ’O I λ1302’ and ’O I^* λ1304’. The subplots showing ’Ar I λ1066’ and ’N I λ1134’ transitions have contamination from the Lyα forest that were included while fitting. The legends as well as the assumption on sub-component redshifts and b-values are the same as in Fig. A.1.
