Evolution of the rotation pole P1 for (184) Dejopeja (symbols) projected onto the reference frame defined by nodal longitude Ω₇ and inclination I₇ of the s₇ frequency line in Fourier representation of ζ = sinI/ 2exp(ıΩ). The initial spin position is shown by the ⊙ symbol. The projection is given on a celestial sphere viewed from an almost pole-on direction. The origin of longitude ϕ, 90° ahead of Ω₇, is located downwards. Four panels are shown for four values of the dynamical ellipticity parameter Δ given at the top. The dashed lines show the meridian and latitude circles. If ζ were to contain only the s₇ frequency term (Colombo model), the spin evolution would follow the solid lines. In the middle panels the spin remains well confined in the resonant zone about the Cassini state C₂ highlighted in gray.
