Total discontinuity percentages

Discontinuity scores based on the Roberts discontinuities. The scores correspond to the percentage of yellow points with respect to the blue points in the “Masked Roberts discontinuities” Figure above.

  • Noisy SWOT discontinuities: 25.16 %

  • Denoised SWOT discontinuities: 0.12 %
