Notes. Also listed are the central velocities for the CII and OI absorptions measured with FUSE (Bar10). The similarity between the four measurements shows that the COS and FUSE wavelength scales here agree very well. Column-densities are in cm-2 and velocities in km s-1. (::) Means a highly uncertain column. (*) From Barstow et al. (2010); (**) total absorption centroid.
