Fig. 4. Characteristics of a luminescent display train during stationary (shaded)
and helical (nonshaded) phases. (A) Mean pulse intensity (as a percentage of
first pulse). Helical phase pulse intensities are approximately 10% of the
initial stationary pulse (N=16). (B) Mean pulse duration: pulse
duration decreases rapidly during the stationary phase, then only slowly
during the helical phase (N=16). (C) Mean interpulse interval.
Interpulse intervals decrease rapidly during the stationary phase, but are
highly conserved during the helical phase (N=85 pulse 1, see
Table 2 for remainder). (D)
Mean interpulse distances. Vertical distance increases during the stationary
phase, then levels off during the helical phase, but there is no trend for
horizontal movement during the course of a display (N=85 pulse 1, see
Table 2 for remainder). Bars
indicate standard errors. For C and D the points are interpulse
values so points occur between pulse numbers.
