A deterministic sampling scheme using sample extensions gives analytic Bayesian posteriors for travel time tomography from 51 forward simulations, but the results are biased because extensions cover limited space and parameter correlations are ignored.

A Semi-analytic but Biased Uncertainty Assessment Method using Sample Extensions, Analysed for Nonlinear Travel Time Tomography
A deterministic sampling scheme using sample extensions gives analytic Bayesian posteriors for travel time tomography from 51 forward simulations, but the results are biased because extensions cover limited space and parameter correlations are ignored.
