Number of unique pairs, N_D, within the 616 possible 1 g final mass fireballs observed by the GFO-FRIPON-EFN with D values below a limiting threshold (red line) compared to the predicted number based on random associations (blue circles with error bars) for D_{S H}, D′, and D_h. The blue circles represent the mean number of pairs identified between two 616 random samples drawn from the possible 1 g fall PDF (Fig. 4) from 500 iterations of KDE sampling. The blue-shaded indicates a zone encompassing three standard deviations. The number of low-D value pairs corresponds very well to the predicted number based on random associations, indicating no substantial evidence supporting streams in the fireball dataset.
