General Description

• This program is the continuation of a large project; in P72, P73 we obtained
   data for 19 GCs,
  and here we will observe M54, the GC tied to the Sgr dwarf galaxy.
  
  The goal is to derive abundances of Na and O from the analysis of spectra taken
   with HR #11 and HR #13 and the detailed chemical composition (Fe, alpha-elements,
   etc.) from the fiber-fed UVES Red  Arm.
  
  Please, complete ALL M54A (prior. 1, HR11 & HR13) OBs before the M54B (prior.
   2, HR13 only) OBs
  
  We attached 2 finding charts to each OB; the first one is based on the DSS, the
   second on a WFI V-band frame and is useful to understand that our FACBs and targets
   are isolated.
  
  VLT Guide star: 19273407, R=11.85
  FACBs: 3800102 R=14.56, 2300023 R=13.48, 4207583 R=13.66, 4104119 R=13.710

Waiver Requests

• WaiverID:  081.D-0286A.01 
  Dear Sirs,
  we ask for a waiver regarding our proposal 081.D-0286 "The Na-O anticorrelation
   in M~54, the closest, high mass extragalactic Globular Cluster", PI E. Carretta,
   on FLAMES.
  As already explicitly said in the proposal form, and as already successfully done
   in the past (see 073.D-0211), we ask to submit OBs in Service Mode longer than 1
   hr total. We would like to have OBs of about 1.5-2 hr in order to increase the efficiency
   of our program and the S/N of individual exposures.
  Thank you for your attention,
  Regards
  Eugenio Carretta
