This image created with the
spectrum intercept algorithm
is based on the dynamical system characterized by the expression,
where θ'' is the second derivative of θ with respect to time.
The parameter values are b=1.96, μ=0.04.
This image differs from the Mad Eye image by b=1.96 instead of 3.33, μ=0.04 rather than 0.0133 and a different domain.
