Scaling of the amplitude of the oscillator as a function of δ for the adimensioned system. Amplitude of (δW) is plotted as a function of time t (not rescaled). The amplitude of δW does not depend on δ in the limit of small δ, this shows that the amplitude of W scales as 1/δ. Parameters are a = 3, b = 5, c = 10, d = 1, and δW = δF = 0.
