We compare results of previous simulations of a simple model of DNA denaturation to the predictions of the Poland-Scheraga model. Concentrating on the critical region of the latter model we calculate both thermodynamic quantities and the distribution functions measured in the simulations. We find that the Poland-Scheraga model yields an excellent fit to the data, provided (i) we include a (singular) factor weighting the open ends of the doubly stranded chain, and (ii) we keep the leading corrections to the finite size scaling limit. The exponent c1, which governs the end-weighting factor, is fairly well determined: 0.1
