Comparison between synthetic data sets generated using the parameters in the maximum likelihood function for the Weibull and Gaussian disorder distribution and the experimental data set of ubiquitin. The constant solid lines are the parameter values obtained from the maximum likelihood function in Eq. 3 and the dashed lines are their standard deviation. Fitting the three data sets using the Weibull distribution gives the fluctuations in parameter a in (A) and b in (B) and using the Gaussian disorder distribution gives k_F in (C) and σ in (D). The ubiquitin data and the synthetic Weibull distribution behave similarly above t_c = 3 s in all cases, but the synthetic Gaussian distribution is significantly different.
