Estimates of locus-specific effects αi, from BayeScan analyses, for each outlier locus in all the inter-host comparisons where it was detected as an outlier (in China and in France).

The average of αi over all these pairwise comparisons is also provided. These values are a proxy for the nature and strength of selection: positive αi values suggest divergent selection while negative values suggest balancing selection. Population codes are defined in Table? 1. Marker names are underlined (not underlined) for outliers detected at a 5% FDR (10%) threshold.
