PLoc(start, end, Corrects the spectrum with a two-point baseline and then report the
baseline1, baseline2) location (X-axis value) at which the maximum Y-axis value occurs
between two spectral limits.
PWidth(start, end, Determines the peak width between two spectral limits. Report the
percent) width at which the peak reaches a specified percentage of the peak
maximum.
Pavg(start, end) Determines the average value of the spectrum between two spectral
limits.
Pcut(start, end, Determines the location (X-axis value) of the cut-on or cut-off point
percent) in the specified spectral region. For example, for a region with
increasing Y value, a cut-on point occurs where the increase reaches
the specified percentage of total increase across the region. Here is an
example showing a cut-on point with "percent" set to 60:
