General Description

• The objective of this run is to obtain high resolution, high signal-to-noise
  (>400) spectra of stars which will be used for benchmark tests of synthetic
  spectra and stellar atmosphere models.
  
  Most of the targets (18) are brighter than V=7 and no bright
  companions are in the HARPS field of view. The observations for these
  stars are executed in one OB. No finding charts have been attached for these
  stars. Please note the Special Execution Requirements for bright stars.
  
  Three stars are fainter than V=7. These observations require several OBs,
  which will be co-added to achieve the required S/N. See Special Execution
  Requirements for faint stars. Finding charts have been attached for these stars.
  
  We request standard calibrations for all stars.
  
  For nine stars we request the observation of a spectrophotometric
  standard in the same night at a similar airmass, if possible, but not more
  than three standards per night.
  These stars are K and M stars (with Teff <= 4500K), for which the standards
  will be used to determine the continuum level.
  This request has been added to the OBs for these stars under "Calibration Requirements".

Waiver Requests

• A request for a waiver for finding charts has been submitted on 2007-07-30
   to
  lasilla@eso.org. No answer was received as of 2007-08-01, but it had been
  pre-approved by Gaspare Lo Curto on 2007-07-27.

Critical Observing Condition Constraints

• There are no critical observing conditions constraints associated with
   the run.

Time-Critical Aspects

• There are no time-critical aspects associated with the run.

Special Execution Requirements

• 1) Bright stars (V<7)
  The exposure times have been calculated for a Seeing of 1.2 arcsec, to achieve
  maximum possible S/N.  If the seeing is smaller than 1.0 arcsec, please choose
  a lower exposure time in order to avoid saturation of the CCDs.
  
  2) Faint stars (V>7)
  For three targets, there are several OBs. These data will be co-added to
  achieve the required S/N.
  Preference should be given to the completion of all the OBs on the same
  target, before proceeding with another target.
  The targets are HD 84937 (4 OBs), HD 113083 (3 OBs), HD 140283 (2 OBs).
