HD AlignRT comparison between intended (x) and measured (o) points in the 6DOF workspace, separated by angular motions performed at each of the 13 translational positions, as well as 8 positions in combinations of the three translational degrees of freedom. No rotations (top), pitch (around LR) of 1°(top left) and 5°(top right), roll (around SI) of 1°(middle left) and 5°(middle right), and yaw (around AP) of 1°(bottom left) and 5°(bottom right).
