22. 1 is the energy splitting between thate 1g and state 1e. The other terms in these two equations are explained in the discussion following Eq. (4).
23. We do not include transitions between the excited states 1e and 2e in the model. Including such transitions will not significant effect the results of the model. The model also does not include inelastic scattering between the defect and the electrons flowing through the SET which cause direct transitions between the left and the right wells. Including these processes will introduce more fitting parameters and improve the fit. However, the qualitative behavior of the model will not change.
