Modules and Libraries

Nexus provides a couple of modules that add some basic functionalities and some libraries with predefined object definitions.

Modules

Constants

Module nx.constants with mathematical constants (nx.constants.inf, …), physical constants, like electron mass, speed of light, and so on, e.g. nx.constants.NuclearMagneton. See constants.

Conversions

Module nx.conversions with functions to convert various properties into different units, e.g. nx.conversions.VelocityToGamma() or nx.conversions.WtToAt(). See conversions.

Data

Module nx.data with functions to load and manipulate typical data sets, e.g. nx.data.load(). See data and Data processing tutorial section.

Euler

Module nx.euler with functions to work with Euler angles, e.g. nx.euler.TransformationMatrixToZYZEuler(). See euler.

Theory

Module nx.theory with functions for theoretical calculations, e.g. nx.theory.RecoilEnergy(). See theory.

Added in version 1.0.3.

Tools

Module nx.tools with some useful functions. See tools.

Added in version 1.2.0.

Libraries

Moessbauer

Library nx.lib.moessbauer with predefined MoessbauerIsotopes. The naming convention is ElementMassnumber e.g. nx.lib.moessbauer.Ir193. See moessbauer.

Energy

Library nx.lib.energy with predefined transition energies. For nuclear transitions the naming convention is ElementMassnumber e.g. nx.lib.energy.Eu151. For atomic transition it is ElementTransitionname e.g. nx.lib.energy.MoKalpha. See energy.

Material

Library nx.lib.material with predefined Materials. For compounds and alloys the naming convention is Element1Relativeweight1… e.g. nx.lib.energy.Al2O3. For isotope enriched materials with typically 95% enrichment the conventions is Material_enriched e.g. nx.lib.energy.Fe_enriched. See material.

Distributions

Library nx.lib.distribution with predefined Distributions. A variety of different distributions are included, e.g. nx.lib.distribution.Log(). See distribution.

Residuals

Library nx.lib.residuals with predefined Residuals. A couple of different residual implementations are included, e.g. nx.lib.residual.Sqrt(). See residual.
