Logarithm of the L2-norm (blue) and logarithm of the standard deviation (red), for the isotherm stated before, as a function of log(N) (the values of log(N) have been replaced by the N values for visibility).
Simulations are performed at ω = 0 rad.s−1. Linear fit and equations have been added for each curve.
