General Description

• The goal of this programme is the detection and characterization of the
   hypothetical low-mass companion to the Pleiades v=12.16 mag K3V star V 642 Tau.
   To achieve this goal, 9 high precision radial velocities will be taken with HARPS
   during 9 different nights in August 2005.
  
  Exposure time: 20 minutes per OB
  Exposure type: with thorium on fiber B (HARPS_ech_acq_thosimult)
  Total execution time with overheads: 3.6 hours
  
  The sampling of the observations is not important and only one night must be avoided:
   August the 25th-26th because of the presence of the moon in the field.
  
  9 OBs have been submitted:
  
  V642tau_A
  V642tau_B
  V642tau_C
  V642tau_D
  V642tau_E
  V642tau_F
  V642tau_G
  V642tau_H
  V642tau_I
  
  Cross-correlation functions msut be computed using the K5 template. The target radial-velocity
   is 5 km/s.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• The only critical contraint for these measurements concerns the airmass.
   They must be obtained with an airmass smaller than 2. Since the target has a declination
   of +24 degrees, observations not too far from the meridian are mandatory in order
   to match the airmass constraint.

Time-Critical Aspects

• Observations have to be taken during 9 different nights. The night of
   August the 25th-26th must be avoided because of the presence of the moon.
