fun rotationEqdEqj(time: Time): RotationMatrix
Calculates a rotation matrix from equatorial of-date (EQD) to J2000 mean equator (EQJ).
This is one of the family of functions that returns a rotation matrix for converting from one orientation to another. Source: EQD = equatorial system, using equator of the specified date/time. Target: EQJ = equatorial system, using equator at J2000 epoch.
| time | The date and time at which the Earth's equator defines the source orientation. |
