Detailed Description

Base class implementing a longitudinally boost-invariant azimuthally symmetric freeze-out parametrization.

The hypersurface is parametrized using variables:

• Space-time rapidity \eta
• Azimuthal angle \phi
• Variable \zeta defining which parametrizes the hypersurface in \tau-R_T coordinates

This base class implements a static fireball (no transverse flow) of 1 fm transverse radius at \tau = 1 fm/c proper time
