In the Results, in the second paragraph of the section “A toy model of the couplon” (page 261), the sentence “With these simple assumptions, the couplon becomes a deterministic…” should not have included the hyphenated phrase “two-state,” as nopen and casr are not two-state variables. The correct sentence is “With these simple assumptions, the couplon becomes a deterministic dynamical system with two state variables, nopen and casr, governed by a pair of differential equations that appear rather daunting once all the simple pieces above have been assembled.”
