Major Instrument Modes: UVES Dic1_346+580

RA Range: 4.2 - 8.8h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.0-1.5, CLR, 1.2-1.5, 1.0, 30


Pre-imaging run? No! Chilean run? No! Special calibrations? No!
Time critical? No! ToO? No! Carry-over run? No!


Special Remarks:


 

 Simple spectroscopic program aiming at measuring Be and Li abundances 
in solar-type stars of 3 open clusters spanning the age range 0.1-4.5 
Gyr. The goal is to further investigate the nature and evolution of 
mixing in the stellar interior of main sequence (MS) solar-type stars. 

 If possible, preference should be given to the completion of all OBs 
available for the same target, in order to avoid the risk a posteriori 
of being unable to detect beryllium. Be aware of different constraints 
associated to the different targets, and (as pointed out by S.Brilliant)
that airmass constraint (1.2) on NGC2516 is 'unfeasible' for specified 
exp.time - it should be considered slightly relaxed.
