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:
 The function is held in the comment field for the object; in
the constants window an
enlarged text window replaces the normal comments window.
 See expressions for more
details on the format of expressions.
 The predefined variables are listed below; any unknown
variables in the function are automatically created as
parameters on simulating, or on right clicking on the node and
selecting "Check Variables"
 Unwanted variables that are no longer in the expression can be
removed by right clicking on the parameter and selecting remove.
Built In Variables
i
