Figure 3


Fig. 3. Saccade amplitude, duration and peak angular velocity are correlated. (A) Histogram of absolute saccade amplitude. The mean value of the data shown in this histogram is 35.2°. Saccades with amplitudes <15° or >150° were not analyzed, since they may represent tracking errors. (B,C) 2-dimensional histograms. (B) Saccade duration, sampled at 101 Hz, loses correlation with saccade amplitude as amplitude increases. (C) Peak angular velocity during a saccade is tightly coupled to saccade amplitude. The bottom of C is truncated at the angular velocity saccade threshold. N=35 flies, n=26535 saccades.
