General Description

• The goal is to compare the radial velocity (Vr) curve morphology of Cepheids
  in the LMC and SMC. For that we need 30 Vr points per target spread over
  each Cepheid pulsation phase.
  The immediate objective in period 74 is to fulfill the Vr curves from previous
  observing runs. For that purpose we need low signal/noise (S/N~5) FEROS spectra
  at the dates specified in the calendars below (_see Appendix_ !).

Critical Observing Condition Constraints

• The goal is to sample the Cepheid _periodic_ Vr curve. The main difficulty
   is
  to observe the Vr curve at an appropriate pulsation phase where no data have
  been taken yet and avoid phases with nearby data available.
  
  Each Observing Block (OB) is one measurement for one Cepheid at a given pulsation
   phase.
  That OB may be observed at the epoch specified in the calender attached bellow
  (see Appendix). Each OB is observed only once.
  No time constrain will be insert in the OB itself since specifying multiple
  observation time windows (i.e. same pulsation phase at different epoch) is
  not possible.

Time-Critical Aspects

• The goal is to sample the Cepheid _periodic_ Vr curve. The main difficulty
   is

  been taken yet and avoid phases with nearby data available.
  
  Each Observing Block (OB) is a measurement for one Cepheid at a given pulsation
   phase.

  No time constrain will be insert in the OB itself since specifying multiple
  observation time windows (i.e. same pulsation phase at different epoch) is

  ** FEROS CCD Binnning **:
  Please note that all the observations are executed with FEROS CCD _binned_

Special Execution Requirements

• **Radial Velocity Standard Stars**
  ----------------------------------
  In order to attach the FEROS radial velocities to the standard ELODIE/CORALIE Vr
  system, radial velocity standard stars are needed. These are bright (mV~6) G-K dwarfs
  which are known to have stable Vr.
  
  ** IMPORTANT **:
  If an OB of a Cepheid has been programed then a standard Vr star OB must also be
   scheduled
  during the same night.
  Such OBs have to be scheduled ONLY if Cepheids OBs will be executed during
  the same night. For example if OB SMC_HV2189_ph10 has been scheduled on 8.10.2004
   then
  the standard star OB for that date (CAL_HD4308_1008) has to be programed.
  A missing standard star OB would severly affect the Vr accuracy of the program.
  
  Because of the rule (Estimated Total Execution Time <= OPC Approved Total Execution
   Time)
  stricly applies, we do not provide a calibration OB for each observing night as
   it
  has been done in period 72. Instead we provide 2/3*Number of Science OBs, assuming
  that most our OBs will be executed during the same nights.
