Histogram of total flux densities resulting from the incorrect predicted associations versus the total flux densities resulting from the ground truth associations. The black dashed lines indicate the 10th, 25th, 50th, 75th, and 90th percentiles of the flux-density ratios. For legibility, the x-axis shows values up to a ratio of 3, but 3.9% of the incorrect predicted associations have ratios higher than 3, with the maximum being 35.9.
