FIGURE 2.

Two example full 360° frames obtained by the capsule (4 camera images, identified by the black lines). Each of the 4 images was divided into 2 sections (blue lines). If <50% was obstructed by feed material, that section was given a score of 1; all scores were then added together to give a total, objective score for the full frame (9‐point scale from 0 [fully obstructed by feed material] to 8 [no obstruction]). In the example frames, the top frame was scored 2 and the bottom frame was scored 8
