Fig. 5

Quantile–quantile plots and optimized Gaussian Mixture Model fit to the VLP widths extracted from the AFM images following 2 h (A, B), 3 h (C, D) and 4 h (E, F) of aging following a single nanoindentation AFM pass. That the Q–Q plots are linear indicates confidence that the GMM accurately describe the VLP distribution. The most simple GMM that yielded a linear Q–Q plot was retained. The included red line represents the perfect, noiseless, data and model.
