Edit Trace Masks
To edit trace masks:
1. Click the Create mask over current trace data toolbar button to create/recreate a mask.
2. Set the smoothing and power offset using the toolbar drop-down lists.
3. Nudge a section of the mask down using the left mouse button.
4. Use the Max Hold button before creating the mask.
Changing the mask in the list affects future traces acquired, but not the status of traces already stored in the database.
