Extended Data Fig. 3: The fine-regolith abundance derived from OTES data is lower than the area of unresolved material measured in Bennu’s images.

Our visual mapping and size measurement of rocks within two OTES spots: a, OTES spots 609493058:610103962; b, OTES spots 609487186:610098206. In both areas, the values of α from our thermophysical solution are smaller than the areas of unresolved materials seen in the images. Given the coarse PolyCam32 resolution, it is possible that there are unmapped particles larger than ls (but smaller than the image resolution) that our thermophysical model detects as rocks and thus do not contribute to the value of α.
