Fig. 15


The C iv λ1548 Å and the C iv λ1550 Å (top) lines of two high redshift metal systems in the line of sight to the QSO B1422+231 are shown in these normalized plots together with the corresponding Lyα and Lyβ absorptions. The data compare well with the observations of these systems with HIRES at Keck at three times the resolving power and from longer integration times published by Songaila & Cowie (1996). With the X-shooter, it was possible to observe all of these lines in parallel exposures within the blue and visual arm. The corresponding Mg II absorptions of the same systems fall in the NIR arm of the instrument.
