Abstract: A Monte Carlo simulation study of the critical and off-critical behavior ofthe Baxter-Wu model, which belongs to the universality class of the 4-statePotts model, was performed. We estimate the critical temperature window usingknown analytical results for the specific heat and magnetization. This helps usto extract reliable values of universal combinations of critical amplitudeswith reasonable accuracy. Comparisons with approximate analytical predictionsand other numerical results are discussed.
