The VCS statistic demonstrates roughly equal sensitivities to both stellar mass-loss rates and magnetic field strength. As its color-plot shows, distances solely quantifying changes in stellar mass-loss rates tend to resemble those explicitly comparing changes in magnetic field. In fact, some of the largest distances involve T4, the run with the strongest magnetic field. We also note large distances between the turbulent clouds T1 and T2 in the presence of strong winds. These clouds have the same magnetic field strength, indicating that the VCS is sensitive to the initial turbulence conditions. We also find the SPS to be sensitive to all simulation parameters, but unlike the VCS, it's sensitivities are not structured.  %We We  find the Bicoherence to exhibit strong sensitivities towards to  stellar mass-loss rates and time evolution, and a weak sensitivity towards magnetic field strength. Changes in rates,  magnetic field strength slightly impact the outputted distances, while introducing feedback greatly impacts them... strength, and time evolution. As time evolves, wind models do become more alike, but they remain largely different from turbulent models. Turbulent models also appear relatively similar to each other. %The observed trend deviates from those of previously considered Intensity statistics, but still  %For purely turbulent runs, we find the Bicoherence to exhibit a binary behavior, similar to that of the Cramer statistic. While it usually yields equal distances for all simulation pairs, the statistic produces a range of values for comparisons involving purely turbulent runs. T3t0 and T4t0 appear to be relatively similar, and different from all other simulations. And, although the distances for pairs (W3T2t0.1, T3t0) and (W2T4t0.1, T4t0) appear to be different, the distance between runs W3T2t0.1 and W2T4t0.1 is found to be similar. %still waiting for HPC to fix python issue, so I can't test out the new distance metric just yet.
