Precession | Precession transformation matrix based on the IAU 1976 theory of precession. Used to convert from the mean of J2000 reference axes to the Mean of Date axes. |
Nutation | Nutation transformation matrix based on the IAU 1980 theory of nutation. Used to convert from the Mean of Date axes to the True of Date axes. |
Rotation | Rotation (main spin) transformation matrix based on the IERS 1996 conventions. Used to convert from the True of Date axes to the pseudo-Earth Fixed axes. |
Pole Wander | Polar motion transformation matrix based on the IERS 1996 conventions. Used to convert from the pseudo-Earth Fixed axes to the Earth Fixed axes. |
