Figure 3.

Bivariate wavelet coherence plot showing the correlation of cut mark damage on the proximal, midshaft and distal sections of left and right femora of the experimental butchery dataset. Arrows indicate that in these two high-correlation areas, both series are in phase (i.e. they covary together in the same direction) in some areas, but in lag (they covary in different directions) in the uppermost right area. The thick black line designates the 5% significance level against red noise and the cone of influence. The thick arrows in between histograms indicate loci of high correlation clustering between both series.
