Fig. 6

Individual PAM time-signals for all three lenses. The signals were normalized to their negative peak value, the average was subtracted, and the signals were shifted in time to have the minimum at time zero. The signal-to-noise ratio (SNR) is given by the ratio of the minimum to the standard deviation of the signal’s noise.
