36. A rather natural locus of effective symmetry, much used in experimental work, is based on linear extrapolation vs T of the coexistence diameter (Formula presented) defined in Eq. (1.2), up to and beyond (Formula presented) Apart from the uncertain nature of the critical singularities in (Formula presented) [as discussed after Eq. (1.2)], the diameter, like the coexistence curve itself, is essentially undefined in the near-critical region of a finite-size simulation owing to the necessarily strong rounding and spread of the density distribution. In the RPM, furthermore, the diameter has a very large slope and, it seems likely, significant curvature so that even naive extrapolation is problematical.

74. We also examined the simulation data for (Formula presented) and (Formula presented) for various values of (Formula presented) The observed behavior is fairly complex; but it can be understood as arising from the finite-size rounding of singularities and discontinuities and from the linear dependence on density implied by Eq. (4.2) in the thermodynamic limit, when it reads, in an obvious notation, (Formula presented) In a sufficiently large and precise simulation, further significant information regarding the Y-Y anomaly may well be extractable from studying these functions. At the level achieved, however, further investigation did not seem promising.
