Due to the marginal detection of C III is the blue components, which may lead to uncertain density estimates, we slightly overestimate the blue wing of the H I features in order to keep the metallicity constant in all 3 components.

Appendix B: Fitted line parameters

Table B.1: Line parameters of intervening N V absorption systems. The ionization parameter has been estimated adopting a Haardt & Madau (2001) UV background at the appropriate redshift normalized to $\log J(1~\textrm{Ryd}) = -21.15$ .

Table B.2: Line parameters of associated N V absorption systems. The ionization parameter has been estimated with an superposition of a Haardt & Madau (2001) UV background and a QSO power law spectrum with a slope $\alpha$ where the relative intensity of the QSO radiation is varied between $0.1 \le J_{{\rm QSO}}/J_{{\rm HM01}} \le 100$ . The quoted uncertainties of $\log U$ represent the resulting parameter range. If no $\alpha$ is given, a pure Haardt & Madau (2001) background has been adopted.
