Gaussian kernel density estimation of the spin-axis orientations computed using the SciPy library (Virtanen et al. 2020) for a very prolate case (p = −6.7). Top panel: (ɛc, ϕc) map. The results in ecliptic coordinates, (λp, βp), are shown in the middle panel and those in equatorial coordinates, (αp, δp), are displayed in the bottom panel that includes the actual observations (in red) of interstellar object 1I/2017 U1 (‘Oumuamua) available from the MPC.
