Accuracy analysis using vertical slices from the target and recovered velocity models and their difference for the single point-source case. A comparison of vertical profiles between the target and the recovered velocity models taken around the latitude of 0\(^\circ\) (a) and the longitude of − 180\(^\circ\) (b) show similar macro features. The velocity difference (blown up by 100 times) shows that the residuals are negligible and lie mostly between an absolute value of 0.02–0.05 km/s. The relative velocity residual confirms the agreement between the target and recovered velocity models.
