    • 2O = 0.4. We note that such resulting stretching would also be rather well compatible with the experimental data. On the other hand, we have checked that the experimental results could also be compatible with Gaussian distributions of mobilities instead of asymmetric distributions. In such case, the distribution would have a width of about 1.2 decades.

    • Artifacts in the NS data analysis might overestimate the deviations from VF-behavior of hydration water in some proteins, as shown in Ref.. However, even using the proper analysis procedure, the characteristic times of water tend to deviate from the high-temperature VF-law, as can be seen Fig. 3 of Ref..
