    "abstract": "Attention is drawn to the role played by the size of the system in the\nthermodynamic analysis of particle yields in relativistic heavy ion collisions\nat SIS energies. This manifests itself in the non-linear dependence of K+ and\nK- yields in $AA$ collisions at 1 -- 2 A.GeV on the number of participants. It\nis shown that this dependence can be quantitatively well described in terms of\na thermal model with a canonical strangeness conservation. The measured\nparticle multiplicity ratios (pi+/p, pi-/pi+, d/p, K+/pi+ and K+/K- but not\neta/pi0) in central Au-Au and Ni-Ni collisions at 0.8 -- 2.0 A.GeV are also\nexplained in the context of a thermal model with a common freeze-out\ntemperature and chemical potential. Including the concept of collective flow a\nconsistent picture of particle energy distributions is derived with the flow\nvelocity being strongly impact-parameter dependent.",
