    • (private communication) has pointed out that the staggered dimers are perhaps not an optimal choice for comparison with the columnar dimers because they lie in different ``winding number'' sectors in the context of the hard-core dimer gas model

    • The uncertainty in the estimate of J2(b) may seem unreasonably small, given the large uncertainty in λc in the vicinity of J2(b). However, J2(b) was estimated by examination of the series coefficients for M hat ( π , π ) and M hat ( π , 0 ). At J2= 0.54, every term in M hat ( π , 0 ) is greater than the corresponding term in M hat ( π , π ) and the ratio of corresponding terms increases with order; in contrast, at J2= 0.52, the ratios of terms in M hat ( π , π ) to corresponding terms in M hat ( π , 0 ) increases wth order, and exceeds 1 at O ( λ4).
