Notes. The min(log10(rlim)) denote the minimum limit lower limit values found when the analysis is repeated with different energy scales shifted by (0%, ± 15%), which should account for the main contribution of systematic uncertainties. Additionally, the number of parameters npar and the AIC and p(AIC) values are provided for the case of an un-shifted energy scale.
