Log-log histogram showing the relative uncertainty of data points, i.e., the ratio of positional uncertainty given by the error covariance matrix over the nearest neighbor distance. The majority of data points are far below unity. The concentration of relative uncertainty values at zero indicates that k-distances across resampled data sets are strongly correlated. The 1σ,  2σ, and  3σ lines indicate the percentiles containing 68, 95, and 99.7% of the respective distribution.
