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:
