Estimates of the mean ± standard deviation of the probability density function P ( s , t / s
) for selected state variables. These plots were obtained using the snapshot data (SSI = 50 sec) from 100 simulation runs. The x-axis is time (sec) and y-axis is the number of molecules of each state variables. These plots were obtained from the 'Time-Weighted Analysis' Tool in the BNS Toolbox.
