Fitting amplitudes of the signal in the j-th segment (black points). The horizontal and vertical axes are the number of the segments and the amplitude of signal in the j-th segment, respectively. The asterisk and relative error bar denote the final value and uncertainty of the estimated amplitude, respectively. There are 43 segments in the figure.
