$\sharp$ - Heavy-element line in Ly$\alpha $ forest region of the spectrum; $\ddag $ - line blended with identified line (C IV in System J is blended with O I from System B); ¶ - saturated line; (a) - H I lines are not observable in Systems E, J, F, I and G, in either MMT or Keck spectra. H I lines in System I and 2.Si IV lines in System E are seen in the MMT spectrum.
