| Center | Used to report the selected point and its velocity in the object's central body ICRF coordinate system. The point must be defined in the Vector Geometry Tool. |
| SubPoint(Centric) | Point on the central body where the object's position vector crosses the central body surface. |
| SubPoint(Detic) | Point on the central body surface from which the line in the direction of the surface normal passes through the object's center (object's position vector is used instead of the surface normal when below the surface). |
| SunGlint | Vector from the object to the apparent location of the Sun glint, the point on the central body surface from where the sunlight is reflected back to the object. |
