Algorithms

Uses the Trapezoidal Rule using the absolute value of the regions between the baseline and the curve. Values are determined both before and after subtracting the baseline.

Let
l = the point number (index) of the left limit of the integration range
r = the index of the right limit of the integration range
x = the X increment between data points
base(x) = the baseline

If the baseline is subtracted from the curve, then y = y - base(x) the Area is then given by:
