Figure 4.
Both on-axis and off-axis results are shown for Experiment 2 (two right columns) and Experiment 3 (two left columns). Note that the y-range is unique to each plot and that the x-range is 60 cm for Experiment 1, whereas for Experiment 2 it is 105 cm. In each plot the blue rhombi, the red squares, and the green triangles represent measurements with the resonant B probe, non-resonant B probe, and the non-resonant E probe, respectively.
