Our results for the correlation length {xi}{sub d}({beta}{sub t}) in the disordered phase are compatible with an analytic formula. Estimates of the correlation length {xi}{sub 0}({beta}{sub t}) in the ordered phase yield strong numerical evidence that R{identical_to}{xi}{sub 0}({beta}{sub t})/{xi}{sub d}({beta}{sub t})=1.
