Final shape model for Atira with a volume-equivalent diameter of 4.92 ± 0.95 km viewed along the principal axes. Yellow regions indicate facets that were seen at incidence angles greater than 60° (or not seen at all) in all delay-Doppler images and therefore have shape details that are not well constrained. The model shows the asteroid to be relatively round and shows concavities, seen in the +Y and −Y directions viewing from +Z, that most likely produce the characteristic “flat” edge in delay-Doppler images such as the bottom row of panels of Figure 2.
