Schematic description of the different scanning processes observable for an occulted exoplanet. The green dotted lines indicate the scanning processes during the exoplanet occultation ingress/egress. The red dashed line indicates the scanning process that results from the exoplanet rotation and produces the exoplanet phase curve – this scanning appears longitudinal for an observer as long as the exoplanet spin is close to the projection plane, e.g., for a transiting and synchronized exoplanet. The component labeled “combined” shows the specific grid generated by these three scanning processes.
