atanc

diffsims.utils.shape_factor_models.atanc(excitation_error, max_excitation_error, minima_number=5)

Intensity with arctan(s)/s profile that closely follows sin(s)/s but is smooth for s!=0.

Parameters:

excitation_errorarray_like or float

The distance (reciprocal) from a reflection to the Ewald sphere

max_excitation_errorfloat

The distance at which a reflection becomes extinct

minima_numberint

The minima_number’th minima in the corresponding sinx/x lies at max_excitation_error from 0

Returns:

intensityarray_like or float
