Figure 9. Separated y-component of S1 elastic wavefield in the orthorhombic model (equation 19) with equal to a) 0 (no smoothing) b) 0.2. The final seprated wavefield with amplitude compensation (equation 28) is shown in c). Notice planar artifacts disappearing when the proposed smoothing filter is applied as shown in b) and with the restored amplitude as shown in c). The clipping has been adjusted to enhance visualization and stay constant in all three plots. |

Figure 10. Separated y-component of S2 elastic wavefield in the orthorhombic model (equation 19) with equal to a) 0 (no smoothing) b) 0.2.
