The columns are great circle arc (degrees), source depth (km), taup_time P-wave travel time for a surface receiver, the CPS time96 P-wave travel time. the difference between the two, followed by similar columns for the S-wave time. The comparison is very good. At larger distances the CPS OP-time is actually Pdiff and the S-wave time is SKS.

The columns here are the P, SV and SH travel time, ray parameter and T*
(assuming a frequency independent T* operator). You will notice that
the SV time at 90 degrees is actually that of SKS which that of SH is
actually S
