Objects Overlays Experimental Plot <Prev Next>

IntensityCorrection

This object is placed under an Experimental Plot object to allow the plotted and fitted intensity to be adjusted as a function of the uncorrected intensity or frequency. The value of the expression is taken as the intensity. A possible function might be:

y/(-0.6138 + .00016732*x)

which divides the original intensity (y) by a linear function (-0.6138 + .00016732*x) of position, x. The function will be evaluated for each data point. Notes:
