ATHENA can be used successfully by using relatively few of its capabilities. For instance, it's fairly obvious that you can import data by opening a file using the File menu, change a parameter value by editing the number in one of the little boxes in the main window, or plot data by clicking one of the buttons labeled with the letters E, k, R, or q. There is, however, a lot more to ATHENA at the level of its user interface. Part of making the leap from beginner to expert is learning about the various user interface features.
One aspect of ATHENA's user interface that requires special explanation is the “Show additional parameters” button at the top of the background removal parameters section of the main window. Clicking it, changes the display of the background removal parameters, replacing the main parameters with a set of additional parameters which can be used to fine tune normalization and background removal.

The main parameters can be restored by clicking the “Show main parameters” button. The additional parameters are all described elsewhere in this document.
