Based on the Helmert family of transformations, the Six Parameter transformation is very similar to a Seven Parameter CFR transformation, except it does not contain a scale parameter. This shift also uses a more rigorous variation that does not require the rotation angles to be small to achieve accurate results.
The "SixParameter" DatumShift has the following Parameters:
