Approximate imaging geometries of New Horizons images of example CRs on Pluto. The imaging geometries are approximately two-dimensional (see text). The approximately constant Sun–surface vector is indicated by an orange arrow. The surface–spacecraft vector for each image sequence is indicated by a black (panchromatic) or blue (MVIC false-color) arrow. Numeric incidence and emission angles are provided with their arrows. The appearance of example CRs relative to their Sputnik Planitia surroundings is summarized for each image sequence.
