Different ionisation metal lines (O I, Mg II, Fe II, Si II, Ar I, N I, Ca II, Mn II, Ni II, Si IV, and C IV) associated with the z_abs = 2.326 ESDLA system towards QSO SDSS J0017+1307. The normalised X-shooter spectrum is shown in grey, the continuum is shown as a dashed green line, with the total best-fit multi-component Voigt profile over-plotted in red. The highlighted part of the spectrum (in black) shows the data that were used to constrain the fit. The residuals are shown above each line in areas used for the fit in units of the standard deviation (± 2 σ) from the error spectrum. In some of the plots where there is contamination either from the Lyα forest or from other transitions from different absorber systems, apart from the total modelled profile in red, the modelled profile for the labelled transition is also shown as a dashed blue line. Short vertical marks (or ticks) in black show the location of the different velocity components. The position of blends with the Lyα forest and other absorption systems unrelated to the ESDLA are shown with cyan ticks. There is a velocity shift between the UVB and the VIS arm spectra for some systems (see Ranjan et al. 2020, for more details). The velocity shifted positions, if any, are indicated with magenta ticks. The sub-component redshifts and b-values of neutral and singly ionised gas species, such as Ar I, N I, and Ca II, are tied together. The sub-component redshifts and b-values for Si IV and C IV profiles are also tied together. The saturated absorption profiles for O I and Mg II are shown for reference. The subplot with Fe II is taken from Ranjan et al. (2020) and is shown here just for reference.
