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.
