Consequently, we wish to compare the original published ETDKG fits to a similar cosine analysis of our data. In our work, the phase shift is also varied as a parameter using nonlinear curve fitting. Note that for both the ETKDG and cosine fits, the histogram probabilities must be transformed into relative energies before fitting. We compare the ETKDG and cosine fits to a sum of up to six fitted Gaussian peaks. Code for the nonlinear curve fitting, via SciPy 69 is included at .
