Peak Characterizations, Area

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:
