Explanation of the Image...

This image created with the spectrum intercept algorithm is based on the dynamical system characterized by a pair of coupled equations,
where x' and y' are the first derivative of x and y with respect to time, t.

The state variables here are x and y. The domain of this image in the map of possible states for this system is,
(-9.74, 14.006)/(19.73, 7.6298)

The parameter values are,
a=10, b=0.7, c=-1, d=0.25, ω=12.56, and φ=0.

This image differs from the Stretched image by ω=12.56 rather than 3.14 and the domain being different.
