Combined log-likelihood surface (NA versus τ) for the haploid mtDNA control region and autosomal RAG2 locus. Black and white points indicate the grid of sampling locations. Log-likelihoods at these points are known with certainty, whereas log-likelihoods in the intervening spaces are interpolated. Regions of the parameter space with highest likelihood are shaded black. Only highlighted white points (circles and triangles) fall within the 95% confidence interval. The maximum likelihood estimate (MLE) is indicated by a white triangle. N0 is set to its value for the MLE.
