+    long_description = """
+    Demographic model of dog domestication with the Boxer reference
+    genome, two basal dog breeds, three wolves, and a golden jackal
+    (outgroup) from Freedman et al. (2014).
+    The topology was based on the neighbor-joining tree constructed
+    from genome-wide pairwise divergence (Figure 5A).
+    The parameters of the model were inferred using the
+    Generalized Phylogenetic Coalescent Sampler (G-PhoCS) on neutral
+    autosomal loci from whole genome sequences.
+    Model parameters were calibrated with
+    a generation interval of 3 years (page 3) and
+    a mutation rate of 1e-8 (page 3).
+    Estimated (calibrated) effective population sizes, divergence times,
+    and migration rates are given in Table S12.
+    Migration is constant continuous geneflow from the start and
+    end times of the two populations that define it (section S9.2.3 in S9).
+    While Boxer reference genome was used, no Boxer-specific parameters
+    were estimated in the model, hence Boxer was removed from this model
+    implementation. Thence the ancestral Basenji population with its specific
+    Ne is for the Ancestral (Boxer, Basenji) population.
