| Description:The Illumination_Start_Stop class contains attributes providing illumination parameters as pairs corresponding to the beginning and end of the observation. If either the start or stop parameter is given, both must be provided. If any values from this class are included in the label, the parameters geometry_start_time_utc and geometry_stop_time_utc must be given in the enclosing Geometry_Orbiter class. If a target is specified using the Geometry_Target_Identification class in the Orbiter_Identification class under the parent Geometry_Orbiter class, the start-stop pairs for each illumination parameter provide the range of that parameter in the observation on that target. Otherwise the pair provides the range for the entire field of view. |
