The averages and their respective standard errors listed in this table are obtained from three AIMD simulations at 910 K, 860 K and 800 K. Cl2N2 -> Cl2N2 jumps through Cl-Cl bottlenecks were only observed at 910 K and only between one of the two Cl2N2 -> Cl2N2 site pairs that are connected by a Cl-Cl bottleneck (Table ) which is why we do not report a standard error for this value (marked with *).
