system at $z_{\rm LLS}=4.242$ is detected in the spectrum. We find a sub-DLA at $z_{\rm abs}=3.476$ with log $N_{{\rm H}\,{\sc \rm I}}=20.04\pm0.07$ and $b=32\pm3.9$ km s$^{-1}$. Metal lines from [Fe]{}[ii]{} $\lambda\lambda$ 1608, 1611, [Si]{}[ii]{} $\lambda\lambda\lambda$ 1260, 1304, 1526, [Al]{}[ii]{} $\lambda$ 1670, [Al]{}[iii]{} $\lambda\lambda$ 1854, 1862, and [C]{}[iv]{} $\lambda\lambda$ 1548, 1550 associated with the sub-DLA are covered in the red part of the spectrum. Fig. \[B0952-0115\] shows the best fit result of the [H]{}[i]{} column density.

8.  Q1036-272 ($z_{\rm em}=3.090$). A low-resolution spectrum of this quasar has been previously published [@jakobsen92]. We report a DLA with $\ion{H}{i}$ column density of log $N_{{\rm H}\,{\sc \rm I}}=20.65\pm0.13$ and $b=35\pm5$ km s$^{-1}$ down to Ly$\beta$ at $z_{\rm abs}=2.792$. Several metal absorption lines from [O]{}[i]{} $\lambda$ 1302, [Fe]{}[ii]{} $\lambda\lambda\lambda\lambda$ 1144, 2344, 2374, 2382, [Si]{}[ii]{} $\lambda\lambda\lambda\lambda$ 1190, 1193, 1260, 1304, and [Al]{}[iii]{} $\lambda\lambda$ 1854, 1862 are covered in the red part of the spectrum. Fig. \[Q1036-272\] shows best fit result of the [H]{}[i]{} lines at $z_{\rm abs}=2.792$.

9.  QSO B1036-2257 ($z_{\rm em}=3.130$). A damped and sub-damped absorber were previously reported in this quasar at $z_{\rm abs}=2.777$ [@fox09] and $z_{\rm abs}=2.531$ [@lopez01] respectively. A Lyman limit system at $z_{\rm LLS}=2.792$ is also detected. From a
