General Description

• This is a simple programme to monitor variability in a selection of extremely
   luminous stars in the open cluster Westerlund 1. Two aspects to take into account:
   Westerlund 1 is very reddened and very compact. 
  Because of the compactness, only the central ~5' of the FLAMES field are used (though
   some sky fibres are placed near the edge, in very dark regions). 
  There are three runs, which must be carried out spread out through the semester.
   
  We use GIRAFFE with the intermediate resolution gratings.
  In each run, there are two OBs: one takes a long exposure with a blue grating and
   the second one takes an exposure with a red grating LR06 and two very short exposures
   with the LR08. As we are very far into the red, atmospheric diffraction should be
   of little importance and hence there is no problem acquiring with the LR06 setting.
  The configurations have been checked for HA -4 to +4
  The guide star has R=11.5
  The FACB stars are
  F17 R=13.2
  F12 R=12.2
  F22 R=14.4
  F13 R=12.0
  They have all positions and R magnitudes determined by us from the same dataset
   as the targets
  The S/N will vary greatly from target to target and hence is not specified.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• In principle, any sky conditions are acceptable, though a very poor seeing
   will degrade considerably the S/N. 
  The fibre configuration has been tested for -4/+4 hour angle only.

Time-Critical Aspects

• There are three runs, which must be carried out spread out through the
   semester. There is no particular concern about the exact separation between runs
   or even about which run should be executed first.
  
   Obviously, the project will benefit if one of the runs is carried out early in
   the semester, one near the end, and one in between.
  
   The two OBs within a run don't need to be executed consecutively, though the smaller
   the difference in time between the observations, the better.

Special Execution Requirements

• The two OBs within a run don't need to be executed consecutively, though
   the smaller the difference in time between the observations, the better.
