        Collection of axis-based translations and rotations to describe the location and
        geometry of the deflector as a component in the instrument. Conventions from the
        :ref:`NXtransformations` base class are used. In principle, the McStas coordinate
        system is used. The first transformation has to point either to another
        component of the system or . (for pointing to the reference frame) to relate it
        relative to the experimental setup. Typically, the components of a system should
        all be related relative to each other and only one component should relate to
        the reference coordinate system.
