Histograms showing the number of jets unambiguously observed in both "on" (above) and "off" (below) eruption states that occupy particular (scaled) stress intervals for each of the three models examined in Paper 2: (a) time delay, (b) 1:1 physical libration, and (c) right-stepping shear motion. The statistical quantity γ for each model measures the likelihood of an orbital correlation. Values close to unity indicate no statistical correlation.
