The following data are the result of running the above mentioned finite difference forward modeling algorithm on the correct velocity model listed below. These images should give the reader an understanding of the starting point of the data before viewing the results of the migrations in subsequent sections.

All of the images in this chapter have excluded any post processing to highlight any numerical
inconsistencies in the solutions. All of the images in this section are the outputs from the stabilized LSM algorithm. The color images on the left are the updated velocity models and the images on the right are the updated seismic sections. They are both set at the same scale for visual comparison. Compare the results in this section with the results in the depth migration section in this chapter to visualize the resolution enhancing ability of the stabilized LSM.
