Notes. Different systems in the table are separated by double lines. For the fitting of the Lyman series we do not give b-parameters. We note that the fitted transitions are different in each intervening system. The C II line of the z = 2.404 system as well as the C IV transitions of the z = 1.9267 system were not fitted as they are located in the red wing of Lyα of the GRB system.
