Constructor & Destructor Documentation

CracowFreezeoutParametrization()

thermalfist::CracowFreezeoutParametrization::CracowFreezeoutParametrization	(	double	RoverTauH = 1.,
		double	tauH = 10. )

Parameters

RoverTauH	Ratio of maximum transverse radius over the freeze-out (Hubble) proper time
tauH	The freeze-out (Hubble) proper time

The value of parameter tauH does not influence the shape of the momenum distribution. Its value is irrelevant for the sampling of the momenta
