Description

template<const size_t d, double()(double) Log = log, double()(double) Exp = exp>
struct DAS::Thunberg< d, Log, Exp >

Motto: "Greta should not fail"

Alternative automated fitter for steeply falling p_T spectrum, using templates -> in principle, thanks to meta-programming approach (i.e. using templates), execution should be a bit faster
