+\section{Area Under Curve}
+\label{filter:AreaUnderCurve}
+
+Measures the area under the curve by integrating the data points. By default, area measured above ground is considered
+as positive and area measured below the ground is considered negative. The negative area can also be considered as positive
+by changing a filter parameter. The measurement can be performed on the full record or on each cycle.
