Figure 1: (a) A single azimuthally anisotropic diffraction. (b) The diffraction migrated by velocity continuation using correct parameters except , resulting in overmigration along . (c) Migration using the correct , but assuming isotropy. The result is now undermigrated along . (d) Migration using correct parameters. The image is well focused in both directions.
