General Description

• This is a simple FLAMES/ARGUS programme. We want to obtain high signal-to-noise
   ratio spectra in order to derive chemical abundance variations over a spacially
   extended region. All the observations are focused on a single field of the GRB980425
   host galaxy, i.e. on a single Target Setup File generated by FPOSS.
  
  Since specific abundances are of interest, we need to use 6 different filtres, LR01,
   LR02, LR03, LR04, LR05 and LR06, to cover the total wavelength range containing
   the required emission lines. The spectral resolution is not critical, therefore
   we use the low resolution setups. We have relaxed the spatial resolution relative
   to the proposal, we use the finer scale (1:1) with a sampling of 0.52 arcsec/microlens.
  
  We have prepared science OBs of 1h48min and 1h, including overheads. There are 2
   OBs per setups LR01, LR02, LR05 and LR06, and 1 OB per setups LR03 and LR04.
  
  As mentioned in "Special Execution requirements", we would prefer that one OB of
   each setup is executed following the priority order specified in the OBs: LR06,
   LR05, LR03, LR02, LR01 and finally LR04, before redoing the loop with the remaining
   OBs.
  
  The selected guide star in our field has a magnitude R=12.02. Four FACBs were selected
   with magnitudes R=13.49, 13.11, 13.03 and 10.50.

Waiver Requests

• We have submitted a Waiver Request on February 5, 2007 for OBs with exposure
   times up to 1h48min. It was approved on February 6, 2007. The Waiver ID is 079.A-0067A.01.

Critical Observing Condition Constraints

• We have no critical observing condition constraints.
  
  However, please, note that the observating condition constraints we have specified
   in our OBs have to be considered as UPPER LIMITS. 
  
  Better conditions, in particular, in the MOON contraint would be highly appreciated.
   Indeed, after a better consideration of the programme, we noticed that a strong
   moon can have much more critical impacts on the weak continuum of our source than
   first expected. Therefore, although we know that we cannot ask for dark time conditions,
   please execute the programme within the best moon constraint you can. Thank you.

Time-Critical Aspects

• We have no time-critical aspects.
  
  However, please, note that our target is well visible (with the required airmass)
   between mid-June and mid-August.

Special Execution Requirements

• We would prefer that one OB of each setup is executed following the priority
   order specified in the OBs: LR06, LR05, LR03, LR02, LR01 and finally LR04, before
   redoing the loop with the remaining OBs.

Special Calibration Information

• When OBs with the same setup are executed during two different nights,
   please, provide a spectrophotometric standard star for each night, in order to ensure
   an accurate flux calibration of our spectra.
