Notes. (a) y = yes; - = no; ? = doubtful, low significance due to low S/N in the S IV region. (b) Relative to the systemic velocity of the host galaxy at z = 2.3304, which we set as zero. (c) Embedded as C1 in the wide C complex (2730-3250 km s-1). (d) Two subcomponents at -2837 and -2803 km s-1 (low ionization) and -2860 and -2810 km s-1 (high ionization). (e) Wide complex spanning 585-1005 km s-1. (f) Embedded as E1 in the wide E complex (40-390 km s-1). (g) Two subcomponents at -150 and -114 km s-1.
