Notes. Δ/σ is the difference between the maxima of the marginal posterior for clustered and unclustered sources, divided by the mean of the upper and lower 1σ uncertainty of clustered sources. Bold values indicate differences we consider significant (i.e. |Δ/σ|> 0.25). Δ_MAP is the difference between the MAP for clustered and unclustered sources.
