This is a visualization of the movement inference algorithm. The left column shows the horizontal plane and the right column shows the vertical plane. The top row shows the green PMT channel and the bottom row shows the red PMT channel. During the movie, periods of visible movement can be observed. The output of the motion tracking algorithm (X,Y,Z coordinate) is overlaid as a yellow point on the movie. As the preparation moves, this yellow point moves with it, which indicates the motion-tracking algorithm correctly inferring the movement.
