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.
