Distribution of ν_sy (subplot i), z (subplot ii), D_var (subplot iii), median S_X-ray (subplot iv), CRTS F_var (subplot v), and ZTF F_var (subplot vi) of: (a) all blazars of the RFC^† and 4LAC samples (with blue, solid lines); (b) blazars spatially associated with neutrinos having W_T > 0.5 (with red, dash-dotted lines); and (c) blazars spatiotemporally associated with neutrinos via BB95 having W_T > 0.5 (with black, dotted lines). “p_KS” gives the p-value of the KS test, and “ℱ_p > 2σ” the fraction of resampled KS p-values reaching the 2σ threshold. “#” denotes the size of each sample.
