Height probabilities in solid-on-solid models. II

For pt. I see ibid, vol.19, p.L923 (1986). The RSOS-3 model is a sequence of two-dimensional solid-on-solid models with integer heights restricted between 1 and r-1 and nearest neighbours differing by 0, 1 or -1. It has an exact solution manifold with four regimes of distinct physical behaviour along which the height probabilities in the bulk of the system can be calculated. Using some results of the previous letter in this series, the authors calculate the height probabilities for two of the regimes. Appropriate order parameters are defined and their critical exponents calculated.
