Notes. Only lines with intensity uncertainties lower than 40% have been considered (see text).

(a)

Corrected for non-LTE effects (see text).

(b)

Blended with another line or affected by internal reflections or charge transfer in the CCD.

(c)

Recombination coefficients for intermediate coupling (Liu et al. 1995).

(d)

Blended with the O ii 4345.55 line.

(e)

Blended with an unknown line.

(f)

Lines are at the very edge of one order and the overlapping between orders was unsuitable.
