• Specify the weighting function mode (optional). In auto weight, the curve fitter
automatically derives a weighting function based on an initial estimate of pole
locations and on the variance functions—the curve fitter then places this weighting
function in the selected weighting register. The weighting function is used to
emphasize important areas of the curve during a curve fit and to de-emphasize areas of
high variance. You can use user weight to use a weighting function of your own
choosing. The selected weighting register is used as the weighting function during the
curve fit. Thus, the weighting register is not overwritten during the procedure.
• Perform the curve fit. See “To perform a curve fit” which appears later in this
chapter.
• View the curve fit table (and edit if necessary). See“Toeditacurvefittable”which
appears later in this chapter.
