Fig. 6From: Accelerometer sampling requirements for animal behaviour classification and estimation of energy expenditureAmplitude estimations of z-axis accelerometer data of all flying segments from seven pied flycatchers. Comparison between the mean amplitude at different subsampled frequencies on the y-axis and the empirical measured amplitude (at 100Â Hz) on the x-axis. The grey diagonal line in each panel shows the 1:1 ratioBack to article page
