Ratios of the production yields to pions for several particle species as a function of the midrapidity pion yields for pp, \pPb\ and \PbPb\ colliding systems compared to the THERMUS model prediction for the strangeness canonical suppression (continuous curves), in which only the system size is varied. All values except for the \kstar\ are normalized to the high multiplicity limit (see text for details). The upper axis shows the radius $R$ of the correlation volume $V=R^{3}$ which corresponds to the predicted particle ratios. The variations in model prediction curves correspond to variations of the chemical freeze-out temperature between 146, 156 and 166 MeV. Reference p-Pb and Pb-Pb data from
