| The most important are the barycentric and trilinear coordinates. |
| Then, interpolation is done with a barycentric system. |
| In a barycentric space-time reference system, the coordinate time may be interpreted as the time which would be measured by a clock at rest with respect to the solar system barycentre and infinitely far from the planets. |
| The loading cells are placed to 120° and to a barycentric height of the tank to obtain narrow weighting tolerances. |
| One concerns the extension of the relativistic framework for the realization of barycentric coordinate time. |
