Notes. The velocity shift of the components with respect to the N V line is indicated. The last row reports the Doppler parameter b of each component as resolved by the X-shooter observations. (§) Mg II lines are particularly uncertain because they are found in a very noisy region at the end of the NIR arm spectrum. ( ‡ )The V, VI (and partially IV) components of Al II are strongly affected by a sky line and could not be determined. ( † )The IV, V, VI components of S II are blended with the Si IIλ1260 Å absorption.
