Notes: N = The number of participants that produced the AU, % Frames active = Percent of the total 600 frames where the AU was active, # Active = The number of times a participants activated the AU during the 600 frames, % Active at max int = the percentage of active frames where the AU was activated at its maximum intensity, Max int = The maximum intensity at which the AU was activated, Cml int = The cumulative intensity or total of all intensity codes across the 600 frames.
