Notes. Parameters with uninformative priors (α and κ) have lower and upper limits (min, max). The other three parameters (log10ρs, log10rs, and βz) have Gaussian priors characterised by mean μprior and spread σprior. Models A and B have anisotropy and rotation fixed to 0; these assumptions are relaxed in model C.
