Recorded wave field
-
The recorded wave field in the triclinic velocity model was
computed using the ANRAY software package
(Gajewski & Psencik, 1990).
3-D ray tracing is used to calculate the two-point rays of
the reflected P-wave. We then compute the ray-theory seismograms
at the receivers.

In the velocity model with the non-inclined curved interface,
the recorded wave field is equal for all parallel profile lines,
since the layers are homogeneous and the non-inclined curved
interface is independent of the distance perpendicular
to the profile lines.
