The y-axis of each plot shows the natural logarithm of the ratio of the maximum vibrissa displacement to the maximum water displacement. The lighter-shaded curves show the results when drag is not considered and the darker-shaded curves show the results when drag is considered. It is clear that drag in water not only broadens the tuning, but lowers the best frequencies. The predicted curves for thin-side stimulation are similarly shaped, with the resonances frequencies shifted to higher frequencies.
