$^a$ Velocities are measured following \cite{Ledoux2006a}; $^b$ Velocities are measured using the MgII$\lambda2796$ absorption following the method recommended by \cite{Ellison2009}; 
$^c$ Lines redshifted on top of the Ly${-\alpha}$ absorption associated to the GRB or in the Ly${-\alpha}$ forest; $^d$~Saturated line.
