- diffsims.utils.shape_factor_models.lorentzian(excitation_error, max_excitation_error)[source]#
Lorentzian intensity profile that should approximate the two-beam rocking curve. This is equation (6) in reference [1].
- Parameters:
- Returns:
intensity_factor – Vector representing the rel-rod factor for each reflection
- Return type:
array-like or float
