To simulate the experimental measurements dataset, we took a part of the theoretical sM(s) in the range 2.6 ≤ s < 32 Å -1 with a step of ∆s = 0.2 Å -1 , which corresponds to the data from Ref. . To each point, an SD, increasing linearly with the increasing s, was assigned, and each value of the sM(s) was shifted with a Gaussian-distributed random value with a pre-assigned SD (see ESI for details). As a result, the simulated dataset shown in Fig. was obtained.
