Recorded wave field
-
Computation of the recorded wave field in the
models has been performed using the ANRAY software package
(Gajewski & Psencik, 1990).
3-D ray tracing (program anray.for) is used for calculation of
two-point rays of reflected P-wave. Program fresan.for computes
the frequency response at a system of receivers.
Program synfan.for calculates ray-theory
seismograms. History files summarize parameters and execute programs
for all 240 shot-receiver configurations in one profile line.

In view of the fact that the layers are homogeneous and the curved
interface is independent of the distance perpendicular to the profile
lines, the recorded wave field is the same for all parallel
profile lines.
