a) Chords from Occ. A superimposed onto the shape model, as seen from Earth (the north pointing upward and the east to the left), at a rotational phase value of 0.888. b) Same as on top but with Van Vleck’s chord shifted 4.0 seconds so that it matches the projected shape (see Section 4.2). c) Chords from Occ. C overlaid onto the shape model as seen from Earth with a rotational phase of 0.93. Geocentric distance (Δ) is taken into account so that the size of the ellipsoids are to scale.
