ReducedIntensity1D.damp_updated_lorch(s_max=None, inplace=True, *args, **kwargs)[source]#

Damps the reduced intensity signal to reduce noise in the high s region by a factor of 3 / (s*delta)^3 (sin(s*delta)-s*delta(cos(s*delta))), where delta = pi / s_max. From [1].

Parameters:

s_max (float) – the damping parameter, which need not be the maximum scattering vector s to be used for the PDF transform. It’s a good guess however
inplace (bool) – If True (default), this signal is overwritten. Otherwise, returns a new signal.
*args – Arguments to be passed to map().
**kwargs – Keyword arguments to be passed to map().
