The overlapping cylinder model (OCM), which is used in this paper considers three components: the longitudinal and transverse movements of the source and the inverse slope parameter of the particle momentum distribution. A comparison of our model calculations in terms of (pseudo) rapidity distributions with the most recent experiments is presented. A relatively strong longitudinal movement of the source is observed at above 1A GeV. From the SIS energy (1A GeV) to the maximum SPS energy (200A GeV), the same relative strengths of longitudinal movements are observed, and two completely overlapping cylinders can give a description of the experimental data. A stronger longitudinal movement is observed, and two partly overlapping cylinders are needed at higher energy (above 4A TeV).
