  Continuum intensity images from PICARD/SODISM and SDO/HMI covering a 209 days
period in 2011 are analyzed in order to extract mode parameters for spherical
harmonics up to $l=100$. SODISM helioseismology signal is affected by the low
orbit of PICARD and by important gaps and CCD persistence effects. SODISM
intensity signal has a lower signal to noise ratio and duty cycle than HMI and
less modes were successfully fitted over the same period. A comparison of the
rotation profiles obtained from both sets of continuum images shows however
that the results remain compatible within one standard deviation of HMI formal
errors.
