Use points for angle measure refers to the number of data points that will be scanned

at once to determine an angle. The larger the number of points, the less sensitive the

algorithm (ie. the fewer peaks that will be defined).

Editing Peaks:

Editing Peak Boundaries

The boundaries of existing peaks can be readjusted to make the peaks wider or narrower.

To adjust either peak boundary, click on the peak to select it. Next, point the cursor at

the vertical boundary line, hold down the left mouse button and drag the line to the

desired location. When it is in place, release the mouse button.

The data table is automatically updated to reflect any adjustments. Both the peak and the

data in the data table will be blue to indicate that this is a user-defined (vs. automatically

detected) peak.

Manually Adding Peaks

Additional peaks can be defined manually using the Add Peak function (in the

Integration menu). When this function is selected, a vertical line appears. Position the

vertical line so it corresponds to the left edge of the peak, click the left mouse button to

define the left boundary of the peak, then move the cursor to the right edge of the peak

and click again to define the right boundary. The peak area between the 2 limits now

appears shaded, and the data table is automatically updated. Both the peak and the data in

the data table will be blue to indicate that this is a user-defined (vs. automatically

detected) peak. To define a second peak, click the right mouse button to reactivate the

cursor.

Deleting Peaks

A peak can be deleted by clicking on the peak and selecting Remove Peak from the

Integration menu. The selected peak's integration disappears, and the integrated peaks to

the right are renumbered accordingly.

A peak can also be deleted by clicking on its entry in the data table window and hitting

the <Delete> key on the keyboard. To prevent accidental deletions, a dialog box will

open, asking for confirmation.
