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 supported model tokens and their explanations. The parameter index links each scientific parameter to its equation, units and applicable model. Conventions fixes the notation used throughout the reference.

Use the reference with the assistant¶

Use a model's exact name and the parameter or equation link when asking a question. The assistant should identify the experiment type and units before applying an equation, distinguish an active parameter from a stored field, and cite the relevant section. Model availability is scoped to the reference snapshot.

The assistant index provides a machine-friendly entry point; the machine-readable catalogue identifies model and parameter pages. These are a retrieval source for the assistant, not a claim that chat integration has already been implemented.
