Figure 6

Centre: the time-migrated section between CMP 5300–9100 shows the middle slope of profile BGR99-46. Top and Bottom: close ups 1a and 2a are the near offset CMP stacks (141 m–766 m) with incident angles of 1.5°–9.7°. Close ups 1b and 2b are the far offset CMP stacks (2641 m–3266 m) with incident angles of 25.9°–37.4°. The colorscale for the offset stacks is modified to emphasize negative reflections. The areas of interest are marked with black ellipses.
