#expts: Number of 20 min experiments. For reverse-correlation experiments, each experiment presented a different stimulus sequence with the same statistical properties; for step experiments, the same stimulus pattern was presented in each experiment.
#animals: Approximate number of animals, taken by finding the maximum number of animals tracked in a 30-s window during each experiment.
#hours: total observation time in units of larva-hours. Observing 3 larvae for 20 min each would equal 1 larva-hour.
#turns: total number of turns observed and used in analysis.
rms turn size: root mean square turn size in degrees (defined as angular difference in run heading immediately before and after a turn) for the set of experiments.
#large/small turns: number of turns with angular changes larger/smaller than the rms turn size.
#accepted head sweeps: number of times the first head sweep of a turn was accepted, ending in a new run.
#rejected head sweeps: number of times the first head sweep of a turn was rejected, leading to another head sweep.
