Analysis of the freeze-out parameters for RHIC, SPS and AGS based on ${   {dE_{T}} \over {d\eta}} / {{dN_{ch}} \over {d\eta}}$ ratio measurements
  The ratio ${{dE_{T}} \over {d\eta}} / {{dN_{ch}} \over {d\eta}}$ is analyzed in the framework of a single-freeze-out thermal hadron gas model. Decays of hadron resonances are taken into account in evaluations of this ratio. The predictions of the model at the freeze-out parameters, established previously from observed particle yields, agree very well with the ratio measured at RHIC, SPS and AGS.
