EXPGUI, part 5

A.5 Profile pane

The Profile pane is used to edit the profile values as well as their refinement flags and damping value. Note that there will be a set of profile parameters for each phase present in each histogram. New! The "Change Type" button is used to select a new profile type for one or more histogram/phase combinations.

If "Multiple Histogram Selection" mode is set to "All", this pane is disabled. For other settings of this mode, profile values and settings can be collectively modified for groups of histograms.

Note that the order that histograms appear in this pane is determined by the "Sort histograms by" option in the Options Menu.

When more than one phase is present in the histogram, the profiles for all phases are shown.

Pressing the "Change Type" button causes a window like the one below to be displayed.

Note that the default profile values are taken from the instrument parameter file (in the example above, a profile was selected where no such default values were defined and the current values (where appropriate) are taken from the current profile function. Through use of the appropriate buttons, selected values can be retained from the current profile when the function is changed or can be reset to default values. This latter capability can be useful even when not changing the profile type, if the profile terms have refined into a false minimum.
