Distributions of equatorial obliquity and cometocentric longitude of the Sun at perihelion for 1I/2017 U1 (‘Oumuamua). Top left panel: histogram of equatorial obliquity, ɛ_‘Oumuamua, with bins computed using the Freedman and Diaconis rule, while top right panel: uses the Bayesian Blocks technique. Similarly, the cometocentric longitude, ϕ_‘Oumuamua, histograms displayed in the lower panels also use the Freedman and Diaconis rule (left) and Bayesian Blocks (right). Histograms are based on data from Table 1 (see the text for details).
