a) As in Fig. 5, bullets (•) show the spin axis orientation as determined withthe SPC method (Fig. 2). Small dots (·) are the spin vector orientation for a simulated body with inertia moments equal to those derived from the shape of 67P assuming homogeneity, and an E_l = 1.9 × 10^-6 under case 1 assumptions , that is, exactly the same circumstances as those of the simulation shown in Fig. 5a. These data are displayed with a time separation of 1 h. Diamonds (◆), to be compared with the bullet distribution and also with Fig. 5a, correspond to the simulated spin axis orientation at the moments associated with each determination with the SPC method, but now calculated as the average value of the instantaneous coordinates within intervals of 10 h around these moments. b) Lomb periodogram of the simulated averaged Dec coordinates (diamonds) shown in Fig. 6a.
