KCl fluxes calculated as function of the relative conductance for potassium (upper trace) or chloride (lower trace).

For a given curve, the conductance of the co-ion is assumed to have its ground value. The ground values used for normalization were: g_K 85 μS/cm² and g_Cl 25 μS/cm². The corresponding equilibrium potentials were taken to be −95 and −15 mV, respectively. The horizontal broken lines originating from the 50% level intercept the flux curve for the co-ion at a value that would result in the same level of flux reduction.
