22. We measure the MSD of particles that at time t = 0 belong to a given cluster of size s. Clearly at high temperature the MSD of particles that at time t = 0 belong to a cluster of size s is nondependent on s and coincides with the average MSD, as expected for very low bond lifetimes. Decreasing the temperature from 0.65 to 0.15, the bond lifetime increases by many orders of magnitude (see Figures 2 b and 3 a,b), and at the lower values of the temperature considered here, clusters live for the whole observation time window.
