Mounting matrix 8 is a 3x3 unitary matrix. A typical mounting matrix would look like 9 [0, 1, 0; 1, 0, 0; 0, 0, -1]. Using this information, it would be 10 easy to tell the relative positions among sensors as well as their 11 positions relative to the board that holds these sensors. Identity matrix 12 [1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and device are perfectly 13 aligned with each other. All axes are exactly the same.
