Notes. We also included the p-values for the SN types and the diagonal hypothetical distribution that accurately traces the respective flux ([1:1]). Black font boxed values represent those distributions without an underlying causative relationship; i.e., we reject the null hypothesis that the two samples were drawn from the same probability distribution (p-value < 0.05), and both NCR distributions come from different populations. The distribution used for the five continuum-subtracted filters have been rebuilt by proportionally removing the number of zero NCR values in each distribution that correspond to the lowest observed fraction of zeros in an individual distribution (see Sect. 6).
