Profiles of the absorbers along the QSO2 sight-line at the H I Lyα line, N V, Si II, C II, and C IV lines. The black histograms show the continuum normalized data, while the orange lines are the sum of all the Gaussian components of the best fit. The location of the absorbers considered are highlighted with vertical dashed lines, that is, ABS1 (magenta; not present along this sight-line), ABS2 (lime), and ABS3 (gray). The zero velocity is set to the redshift of the C IV strongest component of ABS1 along the QSO1 sight-line, as in Fig. 6. Table 2 gives all the relevant fit parameters.
