Estimated Total Execution Time (hours, including overheads)

• 18.5

General Description

• The main goal of the run is to monitor the radial velocity curve of 5
   Galactic Cepheids
  (20 epochs for each star). We have submitted a total of 5x20=100 OBs, labelled with
  the name of the star and a progressive number from 1 to 20. The OBs can be executed
  with virtually any atmospheric condition. The target star is the bright object at
   the
  center of the finding charts.
  
  The periods of the five target stars are of 15-20 days. Ideally, then, observing
   each star
  once per night over consecutive nights would provide an adequate phase coverage.
   The
  long strech of Service Mode time at the 2.2 telescope in August 2005 seems ideal
   for
  this purpose. In any case, please *do not* execute more than one OB per star per
   night.
  
  The total execution time for the 5 targets in one epoch is just 55 minutes. It should,
  then, be operationally easy to execute the OBs for the five targets for the same
   epoch
  in the same night. This is our preferred strategy, as it would ensure an adequate
   phase 
  coverage for all stars.
  
  In addition to the radial velocity curves, we will measure the chemical composition
   of
  our programme stars, hence the need of S/N=20 for each spectrum.
