Figure 4. Histograms showing the distribution of hair movement angles transformed into the animal’s coordinate system.

0 degrees corresponds to an air current oriented at the cricket from directly in front. A: Summed distribution for experimental measurements from three cerci. B: Summed distributions for three simulation runs using different initial hair positions, using 1×10⁵ iterations to minimize the functional. Both histograms show four characteristic peaks. Note the differences in Y-axis scales between the panels.
