Fitting luminescence data¶
LumiSpy is compatible with HyperSpy model fitting. It can fit using both uniform and and non-uniform axes (e.g. energy scale). A general introduction can be found in the HyperSpy user guide.
The Jacobian transformation may affect the shape, in particular of broader peaks. It is therefore highly recommended to convert luminescence spectra from wavelength to the energy axis prior to any fitting to obtain the true emission energy. See e.g. [Wang] and [Mooney].

Signal variance (noise)¶
