General Description

We aim at observing verified members of the red giant branch (RGB) in
 the Hercules dwarf spheroidal galaxy to get enough S/N to compute chemical abundaces.
 A number of (brighter) foreground stars are also to be observed with GIRAFFE. 25
 sky positions have been allocated to the GIRAFFE fibres.

Coordinates for all our targets are from the Sloan Digital Sky Survey (SDSS). These
 coordinates have been compared with those derived from our own imagaing with the
 INT on La Palma and also, for the brighter targets, with 2MASS coordinates. Over
 our whole field of view these three sets of coordinates agree very well and the
 differences are always smaller than the requested accuracy for FLAMES (ie less than
 0.3 arcsec). Also the guide star and the four FACBs are on this system.

Waiver Requests

083.D-0688A.01.WAV - approved

The waiver request was appproved on the 19 Janaury 2009 (email from Claduio Melo).
 

The waiver asked to be allowed to expose for 60 min per OB instead for the 
about 40 min that a 1hours OB including OH would allow. We asked this in order
to increase the S/N of our primary targets (the RGB stars in the Hercules 
dSph galaxy).
