• Launching PkFit
• Configuration of PkFit
• Example 1: Energy scan; one-dimensional convolution
• Example 2: Energy scan, four-dimensional convolution (not yet available)
• Saving data and results
• Printing results
• Quitting the program

For example, enter the data directory name if the data files are not in the program directory. To define the delete key, click the edit text "Delete key" to select it and press the appropriate key. Remember that the contents of an edit text is not validated until a carriage return or a tab key is pressed.

Click the button OK then, the button "Save" in the "Preferences" menu-bar, and finally the button "Menu1" to go back to the main menu.

• Introduction
• 1. Basic features
• 1.1. Opening a data file
• 1.2. Changing plot scales
• 1.3. Initializing fit parameters
• 1.4. Performing the fit
• 2. More options
• 2.1. Adding a new peak
• 2.2. Adding constraints on fit parameters
• 2.3. Applying an absorption correction
• 2.4. Saving a log file

For example select the item "Graph". The contents of the graphic window will be saved to a PostScript file with extension .PLT (i.e. enscan.PLT in the example 1 case).

Select the item "Print" from the main menu. The graphic window is automatically printed on the current printer. Note that the current printer is defined by the environment variable PGPLOT_ILL_PRINT_CMD.

The session file contains the final values of the fitted parameters for all the data files which have been processed during the current PkFit session. For each data file the corresponding set of parameters is written on the same line. The session file is a plain TEXT file (ASCII file) with a record length of 650, and a coma as column separator. It can be imported by applications such as Kaleidagraph and is convenient for the study of, e.g., temperature dependencies or dispersion of excitations in a series of scans.
