 Program aimed at measuring density variations with a spatial resolution 
from 200 kpc down to a few tens of parsecs, and velocity differences on 
the order of a few hundred meters/s, in gas close to the mean density of 
the universe. In order to study the small scale structure of a z=4 galaxy, 
the program observes the two components (1" separation) of a z=4.5 
gravitationally lensed system. 

 PI would prefer to have the centering done on the faint component (although 
it may be difficult to see it): the PA specified in the OBs (but not marked 
on the FC) will then ensure that also the brighter component falls on the 
slit. It is expected that a large fraction of the blue spectrum will not 
have any signal. 

 Waiver request to submit OBs longer than the canonical 1hour was approved 
under the agreement that the OBs will not be repeated should the conditions 
degrade during the 2nd hour.
