Experimental (gray traces, noisy) and simulated (black traces, noiseless) photocurrents elicited by the same intensity flash superimposed on light steps of varying intensity. (A) Photocurrents generated by the same flash, one that saturated photocurrent amplitude, delivered at the end of 2.5-s light steps of intensities: 171, 773, 8,770, 35,236, and 206,056 VP*/s. (B and C) Time-expanded views of experimental and simulated photocurrents, respectively. Shown are the ends of the saturated flash responses recorded at various step intensities, as labeled. Successful flash simulations were obtained by adjusting the value of from 90 s−1 during the step response to 90 s−1 at 171 VP*/s, 90 s−1 at 773 VP*/s, 52 s−1 at 8,770 VP*/s, 28 s−1 at 33,265 VP*/s, and 30 s−1 at 206,056 VP*/s. The dashed black line in C is the simulated response on a background of 206,056 VP*/s computed without adjusting keeping its value the same as that used to simulate the step response.
