Figure 7.
Time taken to separate the two principal component temporal trajectories calculated for the system under two noise cases described in the text. Plot of magnitude of difference of two standardised series as a function of time `- -'. The point at which the noise input to the two lattices became different is indicated in the diagram as a solid vertical line. The dotted `.' vertical line indicates 30 timesteps after the change in noise input and a second dotted line is 40 timesteps later. Where the dashed `- -' curve crosses the solid horizontal line indicates when the deviation became "large" as defined in text.
