Normalised angular velocity, Ω, as a function of the normalised angular momentum, H, for the 42 asteroids (see also Vernazza et al. 2021, Fig. 6). Predictions for the Maclaurin ellipsoids are shown in blue and those for Jacobi ellipsoids in red. The H = 0 value on the left corresponds to the sphere, and the very flattened objects are on the right. The shaded region corresponds to all ellipsoids with 0.5 ≤ c/a ≤ 1. Though this is a large aspect ratio interval, the region is narrow: this representation is not appropriate for evaluating the compatibility of asteroids with Maclaurin ellipsoids.
