  THERMUS is a package of C++ classes and functions allowing
statistical-thermal model analyses of particle production in relativistic
heavy-ion collisions to be performed within the ROOT framework of analysis.
Calculations are possible within three statistical ensembles; a grand-canonical
treatment of the conserved charges $B$, $S$ and $Q$, a fully canonical
treatment of the conserved charges, and a mixed-canonical ensemble combining a
canonical treatment of strangeness with a grand-canonical treatment of baryon
number and electric charge. THERMUS allows for the assignment of decay chains
and detector efficiencies specific to each particle yield, which enables
sensible fitting of model parameters to experimental data.
