English: The combined motions of the transducer and hydraulic cylinder allowed the incoming photons to be collected in four channels representing +0.11 mm/s, +0.09 mm/s, -0.11 mm/s, and -0.09 mm/s. They collectively operated at a 50% duty cycle, so that out of, say, 80 million incoming photons, 10 million would fit into the time slots of each of the four recording channels. Given these cumulative counts, a Lorentzian curve could be fit.
