General Description

This is the observation of a Damped Lyman alpha system in front of a faint
 quasar.
We aim at high resolution power (R=45 000) and sufficient SNR: in the blue to observe
 molecular absorption lines associated to the DLA, and in the red to observe singly
 ionized associated metals.
The observation consist in 6 OBs: 
-Three identical OBs using setting 390+580 to cover molecular lines in the blue,
 some additional molecular and metal lines in the red.
-Three identical OBs using setting 390+610 to covermolecular lines in the blue and
 metal lines in the red, uncovered by 390+580.

Waiver Requests

Two Waiver Requests were submitted on March, 16th and accepted on March,
 19th.
1) We asked for 1h20 long OBs.
2) We asked for a non-standard setting for 3 OBs: 390+610 with template UVES_dic1_obs_expfree,
 to cover some absorption lines (from ZnII and CrII) not observable with 390+580.
