|---|---|---|
| eAttCoordinateAxesCustom | 0 | Custom reference axes. |
| eAttCoordinateAxesFixed | 1 | The Fixed frame of a central body is the frame in which its topography is expressed. |
| eAttCoordinateAxesJ2000 | 2 | Mean Equator and Mean Equinox of the J2000 epoch (JD 2451545.0 TDB which is 1 Jan 2000 12:00:00.000 TDB). The J2000 axes were considered the best realized inertial axes until the development of the ICRF. |
| eAttCoordinateAxesICRF | 3 | International Celestial Reference Frame. The ICRF axes are defined as the inertial (i.e., kinematically non-rotating) axes associated with a general relativity frame centered at the solar system barycenter (often called the BCRF). |
| eAttCoordinateAxesInertial | 4 | Each central body defines its own Inertial frame computed as a constant rotation from the ICRF frame. Earth and Sun both define their Inertial frames as ICRF itself (i.e., no rotation) and do not provide an additional frame named Inertial. |
