Plots are shown for samples following 2 h (A), 3 h (B) and 4 h (C) of thermal aging. That the Q–Q plots are linear indicates confidence that the GMM accurately describe the VLP distribution. The simplest GMM that yielded a linear Q–Q plot was retained. The included red line represents the perfect, noiseless, data and model.
