English: Occulting silhouettes of the best-fit convex model of Leucus (solid black line) along with the rejected complementary model displayed in light gray. The five panels correspond to the epochs of the five occultation events reported in Buie et al. (2020). The red circles correspond to the starts and ends of the respective positive occultation chords. The red, green, and blue arrows represent the X, Y, and Z axes in the body-fixed reference frame, respectively. θ represents the aspect angle, i.e., the angle between the spin axis and the target-observer direction.
