Estimated Total Execution Time (hours, including overheads)

• 1

General Description

• This is a simple spectroscopic programme consisting of 
  two independent OBs for two different targets in Chamaeleon,
  which should be executed in June or July 2006 (the later, the better),
  whenever the relaxed seeing conditions are met.
  
  The later the observations can be carried out in June/July, the 
  better it is for the science program, which requires a time offset 
  to another run of several weeks (see Time critical aspects).
  However, the airmass should be below 2.

Critical Observing Condition Constraints

• All OBs can be executed under a seeing of 2" and bright time.
  Thin cirrus clouds (inducing absorption up to 0.2 mag) may be present. 
  The airmass should be below 2.

Time-Critical Aspects

• The OBs of this run D should be executed in June or July 
  in order to make sure that there is a time offset of a few weeks 
  to another run (077.C-0831(A)) of this program, which is carried 
  out in April.
  The larger the timely separation between run A and D, the better.
  However, the airmass should be below 2.
  
  Explanation: Run D consists of identical OBs as run A. A timely
  spacing of a few weeks of the two runs will allow a repeated 
  measurement of the radial velocities with a long enough time base
  for orbital period sampling of the two companion candidates.

Special Calibration Information

• A wavelength calibration (ThAr lamp) is needed on the same day with exactly
   the same settings
  as the observations (readout 50kHz,2x2,high, slit width 1.0", central wlgt 860nm)
   and with
   * an exposure time of ~0.1 sec *  (otherwise there will be too many lines saturated!).
