   \caption{The frequency in the corotating frame and magnitude of the maxima of the PDS of the
   gravitational torques from the inner disk are shown for the Jupiter 
   simulations. The values are sorted by the magnitude of the PDS at the maximum. The magnitude of the PDS is related with the amplitude of the oscillations at a given frequency. Polar codes
   have larger maxima and the frequencies correspond roughly to the Keplerian
   frequencies at the gap edges.}
