Notes. Shown are the p-value probabilities for the null hypothesis that the strands and global curves samples for new, intermediate, and old comets are drawn from the same parent populations. Pairwise comparisons (rows) were performed using D_KS on strand parameters k_r and m_r, and global curve parameters k₁ and m₁ (columns). Strand p-values are averages of 100 debiased strand samples. Lower p-values indicate stronger evidence against the null hypothesis, suggesting differences between Oort groups. Pre- and post-perihelion data were considered separately.
