Different ionisation metal lines (Mg II, O I, Fe II, Si II, Mn II, Ni II, Si IV, C IV, and N V) associated with the z_abs = 2.482 ESDLA system towards QSO SDSS J1349+0448. The sub-component redshifts and b-values of C IV and N V are also tied together. ’N V λ1242’ is contaminated and hence the transition was not used for fitting. The Si IV profiles are strongly blended and we could not find any robust solution for the column density tied with C IV. Here, we just show the unfitted spectrum for reference. The cyan tick in the ’Si II λ1526’ subplot represents a blend with an Mg II absorption system at z_abs = 0.8998. The legends as well as the assumption on sub-component redshifts and b-values are the same as in Fig. A.1.
