  The transverse momentum and rapidity distributions of net-baryons (baryons
minus anti-baryons) produced in central gold-gold (Au-Au) collisions at 62.4
and 200 GeV are analyzed in the framework of a multisource thermal model. Each
source in the model is described by the Tsallis statistics to extract the
effective temperature and entropy index from the transverse momentum
distribution. The two parameters are used as input to describe the rapidity
distribution and to extract the rapidity shift and contribution ratio. Then,
the four types of parameters are used to structure some scatter plots of the
considered particles in some three-dimensional (3D) spaces at the stage of
kinetic freeze-out, which are expected to show different characteristics for
different particles and processes. The related methodology can be used in the
analyzes of particle production and event holography, which are useful for us
to better understand the interacting mechanisms.
