0 See footnote to Table A.1 for naming conventions.
1 Instrument that provided the data: U = UVES, H = HIRES, E = ESI.
2 Redshift defined by velocity of strongest low-ionization component.
3 Metallicity on log scale relative to solar. Z = S, Si, or Zn as listed in adjacent column. No ionization corrections have been applied.
4 N V line used for measurement.
5 Is the N V doublet in the Lyman-${\alpha }$ forest? If no, the system is within 5600 km s-1 of background QSO, so ``no'' implies ``proximate''.
6 N V rest-frame equivalent width, measured in the velocity range listed in the adjacent column. Upper limits are 3$\sigma$. In cases marked $\dagger$, the data are partly blended; the measurement listed here derives from the unblended velocity range, and the total  $W_{\lambda}$ could be higher.
7 For detections, $N_{\rm N {\sc v}}$ is the sum of the component column densities from VPFIT. For non-detections, 3$\sigma$ upper limits were calculated using $N_{\rm N {\sc v}}=1.13$ $\times$ $10^{17}W_{\lambda}^{\rm lim}/\lambda_0^2 f$, where $W_{\lambda}^{\rm lim}$ is the 3$\sigma$ upper limit on the equivalent width in mÅ, $\lambda_0$ is in Å, and $N_{\rm N {\sc v}}$ is in cm-2.
