Z~= S, Si, or Zn as listed in adjacent column. No ionization corrections have been applied.\\ $^4$ \nf\ line used for measurement. \\ $^5$ Is the \nf\ doublet in the \lya\ forest? If no, the system is within 5600~\kms\ of background QSO, so ``no'' implies ``proximate''.\\ $^6$ \nf\ 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, $N_{\rm \nf}$ is the sum of the component column densities from VPFIT. For non-detections, 3$\sigma$~upper limits were calculated using $N_{\rm \nf}=1.13$~$\times$ $10^{17}W_{\lambda}^{\rm lim}/\lambda_0^2 f$, where $W_{\lambda}^{\rm lim}$ is the 3$\sigma$~upper limit on the equivalent width in~m\AA, $\lambda_0$ is in~\AA, and $N_{\rm \nf}$ is in~cm$^{-2}$. \\ {\bf List of sub-DLAs with blended \nf\ (QSO, $z_{\rm abs}$, instrument)}: Q0952--0115 3.47570 U; Q1108--0747 3.48179 U; Q2116--3537 1.99618 U; Q2153+1344 3.14198 U; Q2332--0924 2.28749 U. \end{table}
