Fig. 3From: Accelerometer sampling requirements for animal behaviour classification and estimation of energy expenditureExample time-series waveform plots for tri-axial accelerometer data (marked by ax: lateral movement, ay: longitudinal movements, and az: vertical movement) of flying (A), and swallowing behaviour (B). Grey lines are original raw data sampled at 100 Hz. Black lines are waveforms subsampled at 50, 25, and 12.5 Hz. Vertical scale bars in the 50 Hz panel of A and B show scale in number of g units (1 g = 9.8 m/s2)Back to article page
