Determining possible solutions for w, q, and kbend using the Constant FB approach on the fusion data of Imai et al. (13) at ρHA,200 and using rate values in Table 1 for pH 5.2. The ratio Dtest/Dcrit is used to determine if simulations match with the data of Imai et al. If Dtest/Dcrit is <1, simulations are accepted. An example of an invalid solution is shown when w = 3 and q = 3 (olive green line), as noted by Dtest/Dcrit being >1. To see this figure in color, go online.
