Detailed Description

template<class T>
class clipper::TargetFn_sigmaa< T >

simple sigma_a target function
Warning: Convergence of this basis-function can be
unreliable under some circumstances. Use clipper::TargetFn_sigmaa_omegaa instead, except for development purposes.

This class implements the target function for calculating sigma_a. Required is a datalist containing Eo, Ec.

This version simplifies terms in |Eo|^2 and |Ec|^2 which should average out to 1 if the normalisation scheme is consistent with the sigmaa calc.
