Fitting results of experiment. There are two notes in this figure. Note that the⁺means that the results of this curve are obtained by the WLS-DS method withb= 0.5 mV andk= 0.01 (blue lines). Note * means that the results of this curve are obtained by the WLS-DS method withb= 1 mV andk= 0.01 (green lines). The WLS fit is corresponding to the common WLS method which uses the total decay signal to fit. (a) Group 1, (b) group 2.
