- 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:
- excitation_errorarray_like or
float The distance (reciprocal) from a reflection to the Ewald sphere
- max_excitation_error
float The distance at which a reflection becomes extinct
- excitation_errorarray_like or
- Returns:
- intensity_factorarray_like or
float Vector representing the rel-rod factor for each reflection
- intensity_factorarray_like or
