Session 3.3 ______ ___ GNGTS 2023 Figure 2. The VS models from SWT inversion. Straight-ray SWT results are shown at: (a) 2.5 m depth, (b) Y=18 m, (c) X=18 m, and the results of the curved-ray for the same slices are displayed at subfigures (d) to (f). The boundaries of the low- and high velocity blocks are superimposed in blue and red. The black and white arrows mark the blocks in which the curved-ray approach provides better results.
