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.
