help for additional information regarding smoothing data.
In general, start with a 9- or 11-point smooth for a time-base measurement. To select
the proper number of points for wavelength-scan types, first locate the area that re-
quires smoothing—usually this is a peak. Determine the number of data points used to
make up the peak, and then smooth the data using the number of points closest to this
number. To avoid artificially enhancing the data, use the appropriate number of points
to smooth the data. For example, selection of too large a number results in the back-
ground being smoothed into the peak.
