rotationEqdEct

fun rotationEqdEct(time: Time): RotationMatrix

Calculates a rotation matrix from equator of date (EQD) to true ecliptic of date (ECT).

This is one of the family of functions that returns a rotation matrix for converting from one orientation to another. Source: EQD = equator of date Target: ECT = true ecliptic of date

Return

A rotation matrix that converts EQD to ECT.

Parameters

time The date and time of the equator/ecliptic conversion.
