P-down wavetrain separated, after divergence amplitude compensation estimated from VSP. Note the remaining interferences within the signature time window below 1200 m TVD. Hopefully, the relative stability of the first arrival waveshape below 1450 m TVD, would help preserve the targeted intra Dogger reflections within 100 ms two way time after direct arrival, or about 200 m depth prediction below the borehole.
