Extended Data Fig. 3: Resolution tests.
From: Post-subduction tectonics induced by extension from a lithospheric drip

Resolution test based on synthetic structures involving a vertical (profile A to B) and tilted (profile C to D) high-velocity anomaly. Gray dashed line indicates the location of the input synthetic structure. High and low velocity heterogeneities outside the recovered target structures are largely a function of the random noise that is added to the data.
