Thermal phenomenology of hadrons from 200A GeV S+S collisions

We develop a complete and consistent description for the hadron spectra from heavy ion collisions in terms of a few collective variables, in particular temperature, longitudinal, and transverse flow. To achieve a meaningful comparison with presently available data, we also include the resonance decays into our picture. To disentangle the influences of transverse flow and resonance decays in the ${\mathit{m}}_{\mathit{T}}$ spectra, we analyze in detail the shape of the ${\mathit{m}}_{\mathit{T}}$ spectra.
