DSTO-GD-0215Figure 9: Tail Energy. The power is not calibrated, thus has no units.3.3.1 Second Return StatisticsFor the whole of the second return;• The peak power and peak time (time is calculated from the start of the secondreturn).• The half width based on the peak power.• The centroid position as power and time (time is calculated from the start of thesecond return).• The energy of the second return. Called the Ref. 2nd Return for the referenceseafloor depth and Actual 2nd Return for the actual seafloor depth, in theenergy results frame.• The median power.16
