The TIP4P/2005 water simulation runs are split in n W = 80 consecutive segments, each with a simulation length τ W = 0.5 ns, leading to a total simulation time of τ t W = n W • τ W = 40 ns. The size of τ W is chosen, such that the individual segments can be considered statistically independent from one another. For each simulation f W = 2500 frames were recorded, leading to a time-interval of ∆τ W = τ W /f W = 0.2 ps between two consecutive frames. The length d W denotes the cms-MSD a water molecule experiences on average during a simulation run of length τ W , given by
