Sigmoidal "switch"-function governed by the exponential power law of the binding constant (Eq. (16)): The "switch"-functions are used to describe the intensity-dependence of the asymptotic washing level and the characteristic decay time (Eq. (18), see also Figure 5). The parameters "switch" between their minimum and maximum values at the characteristic intensity Icrit≈a'M. It depends on the number of washing cycles used for parameter estimation (see Eqs. (17) and (18)). The limiting decay times are given by τmin = 2/ln(wmin(2)) and τmax = 2/ln(wmax(2)) (see Eqs. (18) and (17)). The sharpness of the step is governed by the exponent γ (see figure).
