Calculate
PeakSearch...
When selected, peak search attempts to locate and create Regions of Interest (ROIs) for any peaks in the spectrum data.
Background Subtract...
This is a special case of spectrum stripping. The detector background is stored in the background buffer, usually for a long
collection time. When background subtract is executed, the livetime fraction of the background spectrum is automatically
subtracted from the contents of the master buffer. This provides a convenient method of removing naturally occurring
background from a sample spectrum and can be very useful when working with low level environmental samples.
The background subtraction effect may be reverted to the unmodified data using the Undo function.
Smooth Data...
When selected, smoothing performs a 3-point averaging of the data currently being displayed. The function uses the
following algorithm to average data in each channel.
(n-1)+(n)+(n+1) .

The smoothing effect may be reverted to the original unsmoothed data using the Undo function.
Display
Show...allows the user to select the spectrum buffer to be displayed..multiple buffers may be simultaneously displayed in
separate windows.
Transfer...allows the user to move File Spectra or the Master Buffer to the Background Buffer.
Calibration...allows the user to show or hide calibration unit values in graphed spectra. This selection is only valid for
calibrated data. If disabled, the horizontal axis is displayed as channel numbers, up to the size of the defined conversion
gain.
Spectrum...Switches the currently selected window display to Spectrum if the user has been in either Peak or Data
Report mode.
