FIG. 5. A single parameter resolution test. The final model (A) was perturbed by raising the 180 m node by 3 m. The
resulting model (B) was used to produce a new arrival time dataset. The inversion of the final model (A) with the
perturbed time dataset resulted to a new model (C). The next model (D) presents the initial perturbation which created the
perturbed time dataset. Model (E) shows the resulted perturbation on the final model crated by inverting the perturbed
time dataset. The models (D) and (E) are little different. The difference is shown in model (F).
