Notes. Since high- and low-ionisation transitions tend to follow different profiles, we denote them differently: high-ionisation components are denoted with capital, Latin letters and low-ionisation components with Greek letters. Most do not trace the same component – exceptions are Aα = AB, Bγ≈ BD, Cα = CB. H i typically follows the high-ions and as such is included in those components. (S): measurement affected by saturation; (B): measurement affected my blending;

^(a)

relative velocity compared to component Bγ at z = 3.351030;

^(b)

b is the broadening parameter for the component determined from the fit to the highest S/N, unsaturated and unblended lines;

^(c)

only transitions in bold have been used in the determining of column densities or upper limits;

^(d)

see Sect. 3.1.1 and Figs. 3, 4;

^(e,f,g)

z = 3.358461,3.359810,3.361463 and b = 65,36,72 km s^-1 respectively.

^(h)

Combined upper limit for BA+ BB + BC;

⁽ⁱ⁾

b = 8.0 km s^-1;

^(j)

true nature of this measurement is discussed in Sect. 4.4.
