(a) The average of first 1000 initial models used in the Monte Carlo search. (b) The standard deviation of those initial models. Grey region denotes the range of initial reflector depths (30 ± 5 km). (c) The average of first 1000 successful models with χ²≈ 1. (d) The standard deviation of those models. Grey region denotes the mean Moho profile with one standard deviation. (e) Percentage difference between the model average from the first 1000 successful models and that from the second 1000 models. (f) Difference in standard deviation for those two model ensembles. Grey region denotes the mean Moho profile with the difference in standard deviation (mostly <0.1 km).
