Estimated Total Execution Time (hours, including overheads)

• 38

General Description

• This is observations of multiple detached eclipsing binaries in the two
   open clusters NGC2243 and NGC2506. The aim is to measure masses of the stars from
   the multi-epoch radial velocities. In addition to the binaries, free fibers are
   used to determine cluster membership for single cluster stars. UVES fibers are used
   for metallicity measurements.

Waiver Requests

• A waiver request for 1.25 hour long OBs was submitted and accepted

Critical Observing Condition Constraints

• .

Time-Critical Aspects

• For each cluster there are 15 epochs of FLAMES observatons of the eclipsing
   binaries. On any given night a maximum of 1 OB for each cluster should be executed.
   That is one OB starting with NGC2243_epoch... and one OB starting with NGC2506_epoch...
  Furthermore please make sure that all 15 OBs for one cluster are not executed within
   15 days, but allow for nights with no observations, if this does not come naturally.
   Optimally the time span from first to last epoch should be at least 30 days.
  
  The 2 OBs named NGC2243_CMD1 and NGC2243_CMD2 are observations of single stars to
   determine their cluster membership from radial velocities. These OBs are not time
   critical and can be executed on either the same or separate nights.

Special Execution Requirements

• The observations are of a mildly time critical nature, as specified in
   the 'Time-Critical Aspects' section.
  
  The finding charts for NGCXXXX_epochY OBs all show the allocated objects for epoch1,
   since most objects are identical for all epochs. The VLT Guide star is indicated
   with a red tilted square, the FACB stars are marked with red squares, and the field
   center is marked with a wide blue circle. All these are identical for all observations
   of this kind. This does not apply to the two OBs NGC2243_CMD1 and NGC2243_CMD2,
   which have different pointings and FACB stars, and therefore different finding charts.
