Data for the bimodal interaction model are compared with those for the Laplacianinteraction model. Special attention is paid to scaling corrections. The limiting infinite size value at criticality forthis dimensionless variable is a parameter characteristic of a universality class. This critical limit is estimated tobe equal to 0.523(3) in the bimodal model and to 0.473(3) in the Laplacian model. |
