Abstract:
The data represent report a 9-night asteroseismic observation program
conducted in January 2007 with the new spectrometer SOPHIE at the OHP
193-cm telescope, on the F5 IV-V target Procyon A. This first
asteroseismic program with SOPHIE was intended to test the performance
of the instrument with a bright but demanding asteroseismic target and
was part of a multisite network. The SOPHIE spectra have been reduced
with the data reduction software provided by OHP.
