Hotspots for the DQO truncation on a Mollweide projection. (a) Ensemble of 10⁵ weighted hotspots, generated using the same samples as shown in Figure 4, with the color bar indicating the transition from low density (black) to high density (yellow–white) regions. Panels (b) to (h) illustrate the wide variety of hotspot configurations (orange), where (b) shows the overlap of nonweighted hotspots for 500 randomly selected samples, and the rest show individual hotspots for six random cases.
