Ensemble-averaged MSD and for a population of molecules in three different regimes: noise-limited, subdiffusive, and confined. (A) Ensemble-averaged MSD versus τ and (B) Cυ in the noise-limited regime, where . (C) Ensemble-averaged MSD versus τ and (D) Cυ in the subdiffusive regime, where α = 0.7. (E) Ensemble-averaged MSD versus τ and (F) Cυ in the confined regime, where L = 60.
