The authors' main claim Utilizing a hydrodynamical model for the freeze-out stage in heavy-ion reactions, we extract from resolved transverse hadron spectra at midrapidity an inverse slope parameter (temperature) $T_{Pb} =$ 120 MeV and an averaged transverse flow velocity $v_{\perp Pb}^{aver} =$ 0.43 c in central collisions of Pb + Pb at 158 AGeV.
