... continued and then downward continued back to the original datum. This is intended as a proof-of-concept, and so data is densely sampled, largely noise-free, and on a flat regular grid, representing a best-case scenario. The 5 sub-images in Figure 1 show the original data (a), the upward continued data...

...-Receiver Seismic Interferometry Appendix: Proof of Equation (1) The proof of equation (1) consists of two main steps: first, we use convolutional form of inter-source interferometry to turn the receiver at x2 into a virtual source. Second, we use the correlational form of inter-receiver interferometry...

It certainly does pay to incorporate on-tine testing methods to reduce the proof test interval and these are discussed later. The method by which the proof test interval...
