  We present a user-friendly tool for the analysis of data from
Sunyaev-Zeldovich effect observations. The tool is based on the stochastic
method of simulated annealing, and allows the extraction of the central values
and error-bars of the 3 SZ parameters, Comptonization parameter, y, peculiar
velocity, v_p, and electron temperature, T_e. The f77-code SASZ will allow any
number of observing frequencies and spectral band shapes. As an example we
consider the SZ parameters for the COMA cluster.
