Model parameters estimates (theta, t, m) for data set A and B. Parameters were converted into demographic units using the following formulas: theta (individuals) = theta/(4 × μ); T(years) = t/μ. The migration parameter 2Nm was calculated by multiplying (0.5 × theta) and m. HiPt, bin with the maximum residence time; HPD90%, 90% highest posterior density interval.
Due to the long-tailed posterior distribution, the HPD90% upper bound was higher than the upper bound of the prior distribution and could not be estimated.
