Normalized high-ion absorption-line profiles for four DLAs with secure N V detections. A low-ionization line is also shown. VPFIT Voigt-profile models are included as solid red lines. In the N V panels, blends are indicated with the label ``Bl'', and tick marks show the component centers in our best-fit model. The velocity zero-point is defined by the DLA redshift. We annotate on the high-ion panels the total column density obtained by VPFIT.

High-ion absorption-line profiles for the four DLAs with marginal N V detections. A low-ionization line is also shown. VPFIT Voigt-profile models are included as solid red lines. In the N V panels, blends are indicated with the label ``Bl'', and tick marks show the component centers in our best-fit model. The velocity zero-point is defined by the DLA redshift.

High-ion absorption-line profiles for the two sub-DLAs with N V detections. A low-ionization line is also shown. VPFIT Voigt-profile models are included as solid red lines. In the N V panels, blends are indicated with the label ``Bl'', and tick marks show the component centers in our best-fit model. The velocity zero-point is defined by the DLA redshift.

Normalized N I absorption-line profiles in six DLAs with N V. VPFIT Voigt component models are included as solid red lines. Blends are identified only when they appear at the velocities of N I absorption.

Normalized N I absorption lines in three DLAs and two sub-DLAs with N V. VPFIT Voigt component models are included as solid red lines. Blends are identified only when they appear at the velocities of N I absorption.
