PP-up and PS-up reflection images converted to time (twt). Main apparent faults are underlined on the bottom display, on BOTH images. The reflectors surrounding the top Bathonien are slightly dipping to NE, and affected by several step faults, attenuated by lateral enhancement and migration. On the right side, the PS image converted to P-wave twt scale is restituted with higher definition due to the shorter shear wavelength. Figure modified from Figure 4.3.3 of Bailey [8].
