Geometry of the occultation on the fundamental plane. The chords that produced positive detections are reported for Didymos, along with their error bars (grey segments). The two profiles for Didymos represent the ellipsoidal model by Naidu et al. (2024) (blue) and the topographic model by DRACO (orange). The chord segments to the left mark the approximate location and length of occultation features seen in the light curves in proximity of Dimorphos. The final profile reconstructed by diffraction Dimorphos is drawn. Light grey ellipses sample its errors on size, flattening, orientation, and position. The nominal orbit of Dimorphos follows the JPL s432 ephemeris.
