Estimated Total Execution Time (hours, including overheads)

• 24

General Description

• With this observational run we plan to obtain 6 radial velocities points
  for each of the 87 EHB target stars in the globular cluster NGC2808.
  In this way we want to search binary stars among these EHB and to measure
  their fraction, period, and spatial distribution.
  If present, these binaries could be a channel of production of EHB stars.

Critical Observing Condition Constraints

• Our targets are relatively faint stars. For this reason
  we need a clear sky, a seeing of 0.8 arcsec, and an airmass less than
  1.6 to reach the expected S/N.
  The moon should be at least at 30 degrees from our target.
  But for us the temporal sempling is very important so we can accept 
  a seeing of 1.0'' and no moon constrains if this help our OBs to be observed 
  as specified in "Time-Critical Aspects" and "Special Execution Requirements" sections.

Time-Critical Aspects

• This service mode observing run (078.D-0825(C)) is a third
  epoch observation and should be taken after about 80 days
  from the first epoch observation.
  The fist epoch observation is the visitor mode 078.D-0825(A)
  program and will begin the 10th of Jenuary 2007, so you must consider
  this date as first epoch.
  We can accept a seeing of 1.0'' and no moon constrains if this help
  our OBs to be observed 80 days after the first epoch.

Special Execution Requirements

• The 4 OBs of this run (078.D-0825(C)) should be observed consecutivelly
  if possible.
  We can accept a seeing of 1.0'' and no moon constrains if this help
  our OBs to be observed consecutivelly.
