fun rotationEclEqd(time: Time): RotationMatrix
Calculates a rotation matrix from J2000 mean ecliptic (ECL) to equatorial of-date (EQD).
This is one of the family of functions that returns a rotation matrix for converting from one orientation to another. Source: ECL = ecliptic system, using equator at J2000 epoch. Target: EQD = equatorial system, using equator of date.
A rotation matrix that converts ECL to EQD.
| time | The date and time of the desired equator. |
