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.
