Detailed Description

Model that interpolates stored amplitude points.

Member Function Documentation

TComplex Elegent::InterpolationModel::Prf ( double b ) const

virtual

Profile function (amplitude in b-space).

Normalisation is such that \( Amp(t) = 2 p \sqrt{s} \int db b Prf() J_0(b \sqrt{-t}) \)

Parameters

b in fm.
