Fig. 9.
Fit to the metal lines at z = 1.65. The long dashed line (zero of the velocity scale) corresponds to the redshift of Fe II and Si II, while the short ticks mark the centroids of the Mg II and Mg I lines. The velocity shifts seen here are indistinguishable from those measured from UVES data by Agafonova et al. (2011) for this system.
