The table contains the estimated parameters for Model 1 (Fig. 3 A) and Model 2 (Fig. 7 A), given as mean and SD. All rate constants have the form $k=k 0 ×e k 1 ×V$⁠. The a and b values represent allosteric factors. SD values are not given for some of the Model 1 parameters, because those parameters were not estimated but calculated (see Materials and methods). SD values are not given for Model 2, which was truncated from Model 1 and adjusted to describe only a subset of the VC data. The voltage sensitivity factors k¹ can take both positive and negative values and their SDs should be interpreted as absolute values on a scale of approximately −0.15 to +0.15 mV⁻¹, typical of voltage-gated channels. In contrast, the SDs of the pre-exponential factors k⁰ and allosteric factors a and b should be interpreted as relative to the estimated mean.
