Posterior marginal density plots of the demographic parameters estimated from the isolation with migration model of Pachón cavefish and S3_surface fish. q0 = 4N0μ (where N0 is the effective size of population 0 [i.e. Pachón cavefish] and μ is the mutation rate), q1 = 4N1μ (where N1 is the effective size of population 1 [i.e. S3_Surface fish]), q2 = 4N2μ (where N2 is the effective size of population 2 [i.e. ancestral population]), t0 = tμ/g (where t is the number of generation since divergence and g is the generation time), m0 > 1 (μ-scaled migration rate from population 0 to population 1 backward in time = μ-scaled migration rate from population 1 to population 0 forward in time), m1 > 0 (μ-scaled migration rate from population 1 to population 0 backward in time = μ-scaled migration rate from population 0 to population 1 forward in time).
