Abstract:
    We conducted a 5-night observing run with the spectrometer HARPS at
    the ESO 3.6-m telescope in August 2006. We selected the 4th magnitude
    F8V star HD 203608, a low-metallicity star of the old galactic disk.
    We reduced the spectra with the on-line data reduction software
    provided by the instrument. We developed a new statistical approach
    for extracting the significant peaks in the Fourier domain.

Description:
    Time series of the radial velocities of HD 203608 recorded with the
    echelle spectrometer HARPS at ESO in August 2006.
