List of energy ranges R where $\ge 3\sigma$ excesses are found by the Bayesian and/or Frequentist fits, and their maximum significance S (Bayesian, Frequentist). The most likely origin of these peaks are $\gamma$ transitions from indicated nuclei; the respective energies $E_{\gamma }$ are taken from [37]
