Notes. The first column is the degree. The second column is the frequency. The third column is the 68%-credible interval quoted when the mode is fitted. The last column provides an indication of the quality of the detection: OK indicates that the mode was correctly detected and fitted; Not detected indicates that the mode was fitted but not detected by the quality assurance test and Not fitted indicates that the mode was detected with a posterior probability provided by the quality assurance test. When an uncertainty and a posterior probability are quoted, it means that the mode is fitted but detected using the quality assurance test with a probability lower than 90%.
