Notes. Statistical tests with three degrees of freedom for spherical isotropy in azimuth and polar angles for the various simulation outcomes for braids Figure-8, model A, I.A.₄^i.c.(0.5), and $I.A{.}_{68}^{i.c.}(0.5)$. We performed 300 simulations for each set of initial conditions. In both sets m_in = 1 and d_in = 0. The left set of runs was performed using the incoming velocity v_in = 0, the right set using v_in = 2. Here R_BSS, R_BB, and R_TS give the value of Rayleigh Chi-squared for the binary-single-single, binary-binary, and triple-single results. Note that the null hypothesis (consistent with isotropy) is met for values ≪3. For values ≫3 the distribution is evidently anisotropic. Note that in all cases p < 0.05, indicating that our results are statistically significant.
