spectrum Used for Absorbance, Transmittance, and
Irradiance modes.
Left Click here with light off.
Caution: Right Click will zero previous dark.

Compute Area [picture of peak area with green]
Left Click here to show the AreaPSD,
Centroid, Peakwave, FWHM, and Centbase
of a peak. If the data cursor is
not on a peak, the icon will seek to a
peak in the closest direction.
Right Click to start dual data cursor
measurement as outlined below.
This information is printed in the graph
title (concatenated to end of line) when
printing a graph.
Compute Area toolbar function details
-------------------------------------
1. Use left mouse click to compute and display:
AreaPSD, Centroid, Peakwave, FWHM, and Centbase
>> Automatically selects closest peak & finds baseline.
>> AreaPSD = integral Area (Power Spectral Density).
>> Centroid = center wavelength of AreaPSD in nm.
>> Peakwave = wavelength of the tallest point.
>> FWHM = Full Width Half Max of peak in nm.
