The list of the identified absorption lines is given together with their fitted column densities and Doppler widths. The modal value of the Doppler parameter distribution for the Ly-alpha lines is = 25 km/s. The column density distribution can be described by a power-law dn/dN \\propto N^{-beta} with beta = 1.5. 12 metal systems have been identified, two of which were previously unknown.
