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.
