Figure 7.　Eigenrays reflected at Walvis Ridge

Figure 8.　Eigenrays at the Ascension receiver

For the rays shown in Figures 6 to 8, Table 2 lists the delay time for the ray as compared to the axial ray, the maximum depth (of the turning point or the reflection), the launch angle at the source, and the number of reflections. For comparison, the table is repeated for refracted rays with similar delays.

Table 2. Comparison of reflected and refracted rays.

Figures 7 and 8 and Table 2 show that the depth of the ray turning points are considerably changed by being reflected off Walvis Ridge. Rays are converted both to steeper (the -5.5 seconds ray) and less steep (both the -5.24 and -4.60 seconds rays) angles at Walvis Rjdge.
