General Description

• NOTE: I could not select the proper stars for each run, since I do not
   know the dates! Therefore all stars are listed for each run and prioritized! 1=highest
   priority!
  
  The obtained high resolution spectra wil be used to measure spectral line bisectors
   in our K giant target stars. The stars have been selected from a sample of K giant
   stars which we have monitored measuring radial velocities. The selected stars show
   (periodic) radial velocity variations with timescales ranging from days to years.
   We would like to probe the spectral line bisectors at the same timescales.
  
  We require high resolution for this program and therefore we choose the high resolution
   image slicer.
  
  The central wavelength (6461.6 Angstrom) has been selected so that there are enough
   non-blended lines in the covered region which are suitable for spectral line bisector
   measurements.
  
  The exposure times have been chosen to reach at least a S/N of about 200-300. In
   poor observing conditions, these should be adjusted so that at least this S/N level
   can be reached.
  
  Exposure times range from 10 seconds for our brightest star up to 12 minutes for
   the faintest stars.

Waiver Requests

• No Waiver Request was submitted

Critical Observing Condition Constraints

• The observations can be performed in all kinds of conditions that permit
   observing. In case of poor seeing or thin cloud cover the exposure times have to
   be adjusted to reach a S/N of 200-300.

Time-Critical Aspects

• No time-critical aspects are present.

Special Execution Requirements

• ---(Empty)---

Special Calibration Information

• In addition to the standard calibrations which are performed (bias, wavelength
   calibration and flatfields) we have provided calibration OB's for dark and sky subtraction.
   It is not important at what time during the run these are obtained.
