blue_sampler.structure_factor

blue_sampler.structure_factor(points, resolution=2000)

Estimate the radial structure factor S(k) via scattering intensity.

Parameters:

• points (ndarray)

• resolution (int)

Return type:

tuple[ndarray, ndarray]

Returns:

• k ((M,) float array — exact wave-vector magnitudes.)

• S ((M,) float array — exact S(k) values.)

Note

beyond a radius fixed to capture 1/4 of the “resolution” budget, ALL allowed wavevectors are sampled to get maximal precision on low frequencies. Remaining budget is shared evenly accross all pertinent frequency scales.
