Sensitivity plots showing the variations in the relative amplitude increase of the peak compliance, the spatial half-width of the peak, and both the wavelength and corresponding frequency of the forcing that produces peak compliance signal as the S-wave velocities of the cylinder and the background are changed. Triangles correspond to the medium shallow mush cylinder of Fig. 3, circles to the small shallow fluid cylinder of Fig. 5, and squares to the large deep mush cylinder of Fig. 6. Values for the original models are indicated with solid black symbols. Solid grey symbols are for variation with a fixed Poisson ratio, hollow symbols are for variation with a fixed P-wave velocity.
