  Changes in the transverse momentum distributions with beam energy are studied
using the Tsallis distribution as a parameterization. The dependence of the
Tsallis parameters q, T and the volume are determined as a function of beam
energy. The Tsallis parameter q shows a weak but clear increase with beam
energy with the highest value being approximately 1.15. The Tsallis temperature
and volume are consistent with being independent of beam energy within
experimental uncertainties.
