| Boundary Points | Points of the area target in its central body centered fixed coordinate system. |
| Bounding Rectangle | Data for bounding rectangle that encompasses the area target defined in its central body centered fixed coordinate system. |
| Centroid All Position | Position data for the area target's centroid in different element representations computed in the object's central body fixed coordinate system. |
| Centroid Eclipse Times | Generates a listing of all eclipse events. Eclipsing events are start and end of periods of partial lighting (penumbra) and periods of zero lighting (umbra). |
| Centroid Lighting AER | Angle and range data describing the apparent position vector of the Sun relative to the selected point. The data is reported in the object's Local horizontal frame. This frame has the Z axis aligned with the inward surface normal direction (minus Z is up) and the X axis constrained toward the local north direction. |
| Centroid Lighting Times | Generates a listing of all lighting events. Lighting events are start and end of periods of full lighting (sunlight), partial lighting (penumbra) and periods of zero lighting (umbra). Note that the Lighting Times data provider reports all computed penumbra intervals, which means that if umbra exists, then two penumbra intervals, each with its own start and stop times, is reported--one before and one after the umbra interval. So, if lighting times that start in umbra are generated, then the first reported penumbra interval corresponds to the times that follow after the first umbra, and the penumbra interval prior to the first umbra is not reported. |
| Centroid Solar Intensity | Percent of the solar disc visible, along with lighting condition and name of obscuring central body. |
| Collection of Interval Lists | A time component that produces a collection of related interval lists. |
