Start here¶

This reference explains the models and numerical conventions used to calculate and fit EasyDiffraction projects. The equations apply across the application, Python and the command line; the feature matrix distinguishes what each interface can do.

Find a physical model¶

Physical models lists each model with the questions it answers, grouped from the diffraction itself to the fit.

Look up a type or parameter¶

• The model catalogue lists the supported model types and what each one does.
• Parameter explanations link each scientific parameter to its equation, units and model.
• Conventions fix the notation used throughout this reference.

Ask an AI assistant about the physics¶

The application's built-in assistant and your own assistant can both read this reference. When you ask a question, name the model and link the parameter or equation; a good answer states the experiment type and the units before it applies an equation.

Your own assistant can start from the assistant index and the machine-readable catalogue, which list every model and parameter page.
