rotationEclEqj

fun rotationEclEqj(): RotationMatrix

Calculates a rotation matrix from J2000 mean ecliptic (ECL) 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: ECL = ecliptic system, using equator at J2000 epoch. Target: EQJ = equatorial system, using equator at J2000 epoch.
