Table 1. Journal of observations of our observing programmes to find and analyse new high-redshift sub-DLAs in 17 z > 4 quasars.
Table 2. High-redshift quasar absorber sample composed of 21 sub-DLAs and seven DLAs.
Fig. 1 shows the best Voigt profile-fitting solutions for these two systems.
Figure 2. The absorber detected towards PSS J0118 + 0320 at z abs = 4.128 (log N H I = 20.02 ± 0.15).
