  1. For each cell the first value is the parameter estimate, second is the lower limit and third is upper limit at 95% level. ---- indicates that no reliable ML estimate was obtained for a parameter, ‡ unreliable estimate or limit due to flat or incomplete posterior probability distribution sampled and ~0 effectively zero, although the lowest 'bin' does not actually include zero (i.e. low gene flow is probable). a, refers to the forward migration rate (per generation per locus) of haplotypes from population 2 into population 1. b, refers to the forward migration rate (per generation per locus) of haplotypes from population 1 into population 2.
