Figure 2

Depicted are IMF2, IMF3, the combination of IMF2 plus IMF3 = IMF2 + 3 and the original signal. The x-axis shows the time in seconds. The vertical green line shows the onset and the vertical red line the end of the fast up-bow movement as identified from the acceleration signal in the original signal. The vertical black line shows the moment, when the bow is retaken from the frog of the bow to the tip for the second fast up-bow movement. One fast up-bow movement took about 0.5 seconds, whereas retaking the bow took about 2 s.
