Session 3.3 GNGTS 2024 Fig.3 – Amplitude and traveltime inversion when a random noise percentage of 0.5% is added to the synthetic data. The unfiltered estimate (solid blue line) becomes unstable, especially for the velocity, but the smoothed, scaled version for all estimates (dotted red lines) remains fairly good.
