The distances from the measurement point on the RT to the measurement point of the
wheel speed encoder in the vehicle coordinate frame should be input. The directions can
be selected from the drop-down lists. If the wheel speed is from a prop shaft then the
distance should be measured half way between the two wheels. The illustrations in the
