Constructor & Destructor Documentation

CylindricalBlastWaveParametrization()

thermalfist::CylindricalBlastWaveParametrization::CylindricalBlastWaveParametrization	(	double	betaSurface = 0.5,
		double	nPower = 1.,
		double	tau = 10.,
		double	Rmax = 6. )

Parameters

betaSurface	Transverse flow velocity at the surface
nPower	The power in the transverse flow profile function
tau	Freeze-out proper time (fm/c)
Rmax	Transverse radius (fm)

The values of parameters tau and Rmax do not influence the shape of the momenum distribution. Their values are irrelevant for the sampling of the momenta
