General Description

• This is a programe to obtain simultaneously GIRAFFE and UVES spectra of
   a large sample of Red Clump stars in the Galactic Disk selected to span galactocentric
   distances from 3 to 6kpc (distances 2 to 5kpc form the Sun), in two fields (that
   we cann ogle2425 and b2). The spectra will be used to derive abundances of alpha
   elements, iron, and heavy neutron capture elements.
  The expected spectra should have relatively high S/N (S/N~20-150 in individual exposures
   and S/N=50-200 in the combined spectra). A single UVES setup (R580) is used for
   each star, while the GIRAFFE spectrograph is used in 3 different setups to cover
   all lines of interest: H13, H14B and H18.
  The stars are of magnitudes I=12.2 to 14.5 (but these stars are significantly reddened
   to their V magnitudes can reach almost V=17). Each GIRAFFE setup requires from 3
   to 5 OBs of 45mn to 1h each.
  
  ATTENTION: Note that the reference star in FACB#85 in the field ogle2425 has a companion
   6" to the North
  
  The total sample breaks up into:
  - ogle2425, GIRAFFE-H13 + UVES-R580 : 3 OBs of 54mn	prio1
  - ogle2425, GIRAFFE-H14B + UVES-R580: 5 OBs of 1h	prio1
  - ogle2425, GIRAFFE-H18 + UVES-R580: 3 OBs of 38mn	prio2
  - b2, GIRAFFE-H13 + UVES-R580 : 3 OBs of 53mn	prio1
  - b2, GIRAFFE-H14B + UVES-R580: 5 OBs of 1h	prio1
  - b2, GIRAFFE-H18 + UVES-R580: 3 OBs of 38mn	prio2
  
  
  To insure that the spectra are usable even if the programme cannot be 100% completed
   (unlikely event we hope ;-)), we request that ALL OBs of one setup are completed
   before moving to the next setup, and that both the H13 and H14 of one field are
   completed before moving to the second field.
  To reflect this, we have given a lower priority to the H18 setup which does not
   have as much importance as H13 and H14B.

Critical Observing Condition Constraints

• - The most critical constraint is the moon distance: the fieds are extremely
   close to the moon close to fullmoon in May and June. We request that the moon distance
   is >35degrees
  - Seeing is also critical (<=1.0") for the fainter objects (also the most important
   for the program because the most distant) in each field to reach the needed S/N.
