Plots illustrating how randomising the phase information affects the resulting light curve in the EMP13 algorithm. The top row is the entire simulated light curve with slope β = 3 using the TK95 algorithm. The bottom left-side plot shows the light curve obtained from a 40-year segment of the entire light curve, which has been run through the iterative step of the EMP13 algorithm. The right-side plot shows the result of the same iterative step when the entire light curve has gone through it, and only after the iterations has it been cut to a 40-year segment. The PDF used for the EMP13 algorithm was Gaussian with a mean of zero and a standard deviation of one.
