Detailed Description

template<class T>
class clipper::SFweight_spline< T >

Structure factor weighting by sigmaa-related spline method.

Perform structure factor weighting to obtain likelihood weights for structure factors.

This implementation uses a single list of reflections for both scaling and sigmaa, thus the only relevent usage flags are NONE/BOTH.

The number of spline parameters or the number of reflections per parameter may be specified. If either is zero, the other takes priority. If both are non-zero, a compromise value is used.

Structure factor weighting (sigmaa) definition.

In the implementations, this function will do the actual structure factor weighting calculation

Parameters:

	fb	Output best map coefficients.
	fd	Output difference map coefficients.
	phiw	Output phase and figure-of-merit.
	fo	Input observed structure factors.
	fc	Input calculated map coefficients.
	flag	Input flag indicating what to use this reflection for.

Returns:

true on success.
