This line is used on recall of the efficiency table to select the fit type to be used.
After the fit type comes the total calculated source uncertainty, the number of nuclides in the source uncertainty calculation, and the list of nuclides used in the uncertainty calculation. The total is the individual uncertainties added in quadrature.
To add an energy to the table, enter the values directly or click Select from Lib, then click Add
New. To delete an energy, select the energy and click Delete.
To change the values for an energy, select the energy, enter the new values directly or click
Select from Lib, then click Update to record the changes (you must click Update or the changes will not be made).
When finished, click Save As... to rewrite the new file to disk. To discard the changes you have just made, click Cancel; a dialog will verify that you want to discard.
5.3.3.13. The Efficiency Graph Control Menu
Figure 112 shows the control menu for the graph of efficiency vs. energy. It contains selections to turn a Grid on/off and to switch from Log/Log to Linear axes. The graph can also be Closed
(removed). If closed, it can be redisplayed with the Graph command from the Efficiency
Calibration Sidebar’s control menu.
5.3.3.14. The Efficiency Table Control Menu
Figure 113 shows the control menu for the table of efficiency vs. energy. It contains commands to Print and Close the table. If closed, it can be redisplayed with the Table selection from the
Efficiency Calibration Sidebar’s control menu.
