1. FLAMES – an overview
Features & points to be aware of, relevant to the observer. In addition to p2pp, there is FPOSS.
Layout of FLAMES; link to GIRAFFE and UVES via Fiber Positioner; 2 interchangeable plates – when one is observing the other configures
GIRAFFE: MEDUSA / IFU / ARGUS (on only one plate)
UVES: higher resolution, typically brighter objects. Independent exposure times and number of exposures. Light loss if not same wavelength.

2. FLAMES Telescope guide star (9 ≤ R ≤ 11) FACB stars, 3-4 needed
Object fiber
A typical field… FPOSS software to help place the fibers.
Astrometry very important, better than 0.3” – FACBs must be in same astrometric system. GS/FACBs must be good choices.
guiding on setup wavelength of GIRAFFE – careful if UVES has different setup
sky fibers (assigned as you wish)
