Waveform modeling of core phases at very long distances (150o +)-Model PKP-BC & PKP-Cdiff near the C-caustic (150o-160o) to
constrain seismic parameters such as velocity, its gradient and
intrinsic attenuation just above and at the inner core boundary
-Model selected phases PKIKP, PKIIKP etc. at near antipodal
(180o) distances to constrain seismic velocity, texture & intrinsic
attenuation of the shallow and deep inner core.
