| Body Axes Orientation | Reports the orientation and angular velocity of the Body axes of the object with respect to a selected reference set of axes.
The reference set of axes can be selected from any axes in the Vector Geometry Tool owned by the object.

Note that the Eclipse Summary data provider reports the start and stop times of penumbra which, if umbra exists, occur before and after umbra, respectively.

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. |
