• 1.6

General Description

• This program aims at determining precise radial-velocities for a set
  of stars known to follow well defined solar-type magnetic cycles. 
  The goal is to follow this stars for several years, and to check if there are
  radial-velocity variations during the cycle, that could be
  missinterpreted as due to the presence of a long-period giant planet.
  In the OB's, multiple exposures are done to avoid CCD saturation (conservative 
  seeing of 0.4'' considered); long total exposures are needed to
  average the noise induced by stellar acoustic modes.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• Good seeing is not critical, although a seeing better than 1.4'' is
  important (although if not possible, we prefer to have the OBs executed with 
  worst seeing conditions anyway). The sky should not be very cloudy neither, 
  or else we might expect radial-velocity errors and low S/N. The 1m/s 
  precision is our goal. Moon is not relevant (if not too close to the target).
  The goal in terms of S/N is to have >=35 in order 6.

Time-Critical Aspects

• Run A: OBs done for observability in October
  Run B: OBs done for observability in November
  Run C: OBs done for observability in late December/beggining of January
  Run D: OBs done for observability in early February
  Run E: OBs done for observability in March

Special Execution Requirements

• No special execution requirements

Special Calibration Information

• Since the goal is to have precise radial-velocities, we need to use a
   
  simultaneous ThAr calibration technique.
