CAFOS B-100 spectrum of VPMS J1708+4332 (arbitrary units). Identified absorption lines, from absorber systems at three different redshifts z, are marked by vertical lines with colours corresponding to z. Dashed vertical lines indicate common transitions, and dotted lines mark unusual ones. N V and C IV denote the line doublets N Vλλ 1238.8, 1242.8 and C IVλλ 1548.2, 1550.8, respectively. For comparison, the redshifted (z = 2.345) and arbitrarily scaled SDSS quasar composite spectrum (Vanden Berk et al. 2001) has been over plotted (magenta).
