The NA57 experiment at the CERN SPS has measured the production of strange and multi-strange particles in Pb-Pb (and p-Be) collisions at mid-rapidity. The collective dynamics of the collision is studied in the transverse and longitudinal directions as a function of centrality and beam momentum and analysed based on hydrodynamical models. Central-to-peripheral nuclear modification factors at 158 A GeV/c are presented and compared with other measurements and theory.
