General Description

We want to observe field and cluster stars in the LMC in order
to probe the chemical evolution of the galaxy. We want to observe three
clusters: NGC 1718, NGC 1841, and NGC 2257 with relative field stars. 
Combining observations obtained with GIRAFFE and UVES spectrograph 
we will be able to measure the abundances of many elements (Si, Ca, Ti, Sc, V, Fe,
 Ni, Y, Ba).

Critical Observing Condition Constraints

Our OBs should be observed with variable sky (thin cyrrus) or better,
 a seeing<=1.0 arcsec,
grey time or better (lunar illumination<=0.7), and the moon at a distance greater
 than 4-5 
hours (>=70 degrees) from our targets.
Being our objects close to the South Pole, the airmass is generally high. For our
 observation
NGC1841 should be observed with arimass<2.2, while NGC1718 and NGC2257 should
 be observde 
with airmass<1.6.
