Results of the search for SBLAs in the X-Shooter spectrum of the quasar J200324.14-325144.8. The original spectrum (light gray) has been continuum-normalized, convolved with a Gaussian filter to match the resolution of BOSS, and re-sampled into a wavelength grid with a constant bin size of 138 km s⁻¹ (black). The pixels selected as SBLAs (orange) in the region 1041 Å < λ_RF,QSO < 1185 Å (that is, excluding the gray shaded regions) have a transmitted flux within the range −0.05 < F < 0.25 (blue shaded region). Known LLS are shown as green diamonds. We also show LAEs that are matched (filled purple stars) and not matched (empty purple stars) to at least one SBLA within R < 300 kpc and |Δv| ≤ 300 km s⁻¹ in Section 4.
