Phase curves and observing geometries. We computed reflected and emitted light curves for 3 inclinations as follows: 90, 60, and 30° corresponding to subobserver latitude of 0, 30, and 60°, respectively (as the we assumed a null obliquity). The subobserver latitude is indicated with a red line. In Appendix B, phase curves are shown only for an inclination of 60° (the median value for randomly oriented orbits).
