 The program aims at determining the Zn abundance in 5 DLAs, in order to 
verify if the spin temperature anti-correlates with metallicity (i.e. 
with [Zn/H]). 

 Different settings are used in order to cover the spectral regions where 
the (202.6nm) ZnII lines are expected. The only critical object is 0235+164, 
for which the ZnII line should fall around 308nm. Since this target is 
also highly variable (and variations are not predictable) its magnitude may 
range from V=15.5 to 20. Should the object be fainter than V=17, time should 
not be wasted on this object. 

 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 time exceeding the first hour.
