		Movie 1 [2.5 Mb] Entropy (normalized to initial postshock value) for the 1D NSE run with rs0 =75 km just above the threshold for explosion (H = 1.02Hcr in Figure 4), showing the growing L=0 SASI oscillation and the beginning of the explosion.
		Figure 7(a,b) Animated [4.0 Mb] Time evolution of NSE run with rs0 = 125 km just above threshold for explosion, corresponding to Figures 7a and 7b.
		Figure 7(c,d) Animated [4.9 Mb] Time evolution of NSE run with rs0 = 50 km just above threshold for explosion, corresponding to Figures 7c and 7d.
		Figure 8 Animated [4.5 Mb] Time evolution of Figure 8, showing secondary shocks for a constant dissociation as well as NSE run, both just above threshold for explosion.
		Figure 17 Animated (L=0 perturbation) [2.4 Mb] Time evolution of Figure 17, showing secondary shocks in the gain region. The initial perturbation corresponds to a spherical transient (L=0).
		Figure 17* Animated (L=1 perturbation) [2.3 Mb] Time evolution of analog to Figure 17, but now with an initial shell with L=1 angular dependence added in the upstream region at t=0, to trigger a SASI mode, corresponding to the upper two panels of Figure 20.
		Figure 21 Animated [2.1 Mb] Time evolution of Figure 21, showing a histogram of vorticity vs. Mach number in the gain region, for a constant dissociation run with χ=3.9, corresponding to the upper two panels in Figure 19.
