Major Instrument Modes: UVES Dic1_346+580, Dic2_346+860

RA Range: 0.6 - 13.8 h

Constraint set (Typical seeing, Transparency,Airmass, FLI, Moon distance): 1.8, THN, 1.4-1.7, 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 determining the correlation 
between O and Be abundances in galactic stars at the halo-disk transition, 
already known to have different O contents. 

 Objects have different priorities (#1) as specified in README file. For 
some targets, exposure times longer than 1h have been used, under the 
agreement that OBs will not be repeated should the atmospheric conditions 
degrade during the time exceeding the first hour. Authorized change of 
target (CD -33 1173 to replace G46-31).  
 
 Requirements: ONE telluric standard star needs to be observed on each night 
one or more Dic1_346+580 OBs are executed. See README file for exact 
association target--telluric star. 8 such OBs have been prepared, although 
there are 10 Dic1 OBs in the need of such calibration star. If possible, the 
2 Dic1 OBs for targets G5-40 and CD -33 1173 should be observed on the same 
night. However, it is important that at least one of the 2 Dic1 OBs of these 
2 stars is executed together with its corresponding telluric standard star.
