Estimated Total Execution Time (hours, including overheads)

• 19:49:00  (20 times 00:59:26)

General Description

• General Description: The aim of the program is to derive the velocity
   curve of
  the spectroscopic binary HD166734 which has a period of 34.5 days. We would like
  to have 20 observations of the spectrum of this star well distributed in phase.
  The best configuration would be one observation every two nights during 40 
  consecutive days. However, ESO Service Mode is not supporting such time
  constraint. Therefore, we hope that 20 observations distributed at
  random (but always separated by a minimum of one full night without
  observation) will lead to a similar phase covering. We prepared 20
  observing blocks numbered from HD166734_01 to _20. They are all
  identical and represent one observation. One observation is made of
  two Science Exposures of 1450 sec each followed by a wavelength calibration
  exposure of 60 sec. The whole observation takes about one hour (with overheads).
  Please execute one OB each night when you have the possibility to do so. 
  
  The ONLY constraint: a MINIMUM two-day separation between two observations.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• No particular constraint. Of course, exposure times have been estimated
   for rather normal or
  slightly bad conditions. If the pointing is through very thick cirrus, there is
   a risk
  of underexposure.

Time-Critical Aspects

• Only one rule is to be followed (Please):
  
  every observation (one OB execution) has to be separated from any other by
  a minimum of one full night without observation.

Special Execution Requirements

• Only one rule to be followed (Please):
  
  every observation (one OB execution) has to be separated  from any other by
  a minimum of one full night without observation.
