3. From the Peak-Based Panel, click on Find Peaks. The peaks and their ROIs will be
highlighted automatically in green.
4. The found peaks can now be edited, if desired, by clicking on the Allow Edit box. The user
can now adjust the centroid and the left and right edges of each peak region. Peaks can also
be added as well as deleted.
5. To add a peak, simply click on the Double Click Adds Peak box. Locate a peak on the
spectrum with the mouse and double click. Another peak region will appear.
6. To adjust the centroid, left or right edges of any peak region:
7. Select a peak using the Selected Peak arrow set. (Default designates the left-most peak as
#1.) The selected peak will appear in purple highlight, while the remaining peaks will be
highlighted in green.
8. Using the Centroid (keV), Left Edge (keV), and Right Edge (keV) arrow sets, adjust
accordingly. (Double arrows adjust the settings in approximately 5 keV increments, while the
single arrows adjust the settings in approximately 0.5 keV increments.)
9. To delete a peak, first select the peak to be deleted using the Selected Peak arrow set. Once
the peak is highlighted, click on the Kill Peak button.
10. When finished editing found peaks, click on Make ROI on the Peak Panel to convert the
found peaks into an ROI Set. A message will display indicating that the ROI Set should be
given a name. Naming the ROI Set can be put off until later, but it is highly recommended
that a name be given now.
