Fig. 8. Average parameters based on different parts of tracks (compare with
Fig. 6). Thin lines correspond
to data based on the four-point track fragments from frames 46,
69, 912 of the bursts; thicker lines correspond to frames
1215, 1518, 1821 (boldest). Observe that the three thin
lines indicating mean velocities almost coincide, i.e. the photokinetic
response starts to develop around 10 s after the laser is switched on. The
symbols correspond to the average parameters measured in the runs with laser
intensity ten times higher than in the standard experiments.
