Prior Probability

Prior Probability

We set prior probability of each model parameter like the following table.

Model parameter	Distribution type	Tuning parameter
# of layer interfaces	Truncated uniform	k_min, k_max
Interface depth	Truncated uniform	z_min, z_max
S wave velocity perturbation	Gaussian	sigma_dvs_prior
P wave velocity perturbation	Gaussian	sigma_dvp_prior
Data noise standard deviation	Truncated Uniform	sigma_min, sigma_max

All tuning parameters listed above are to be given in the input parameter file.
