Pole deviation over 4 yr computed for an ensemble of moments of inertia and initial pole positions. The initial epoch for computing the pole deviation is taken to be 2029 August 1, 12:00:00 TDB, which is approximately the start of Psyche’s science operations. The hatched region between red dashed curves indicates the 5th to 95th percentile region for the pole deviation from the ensemble of integrations. Individual integrations are shown as semitransparent curves colored by the value of ﹩| H\cos \epsilon | ﹩, where ϵ is the obliquity.
