Figure 3

Total NSMS amplitudes Q(t) of the 216 Camp Sibert anomalies as a function of time. The 25 time gates are distributed approximately logarithmically between 191 μs and 25 ms. The Q-values are shown in the same colors and with the same markers as in subsequent figures, with the black line denoting the median Q for each group. The 15th time channel, corresponding to t = ms, is highlighted; the ratio has been found to be a robust classifier. The gray pentagons correspond to Cell no. 7, which we study in detail in the main text. The thinner dotted lines show the two false alarms from Figure 6, also depicted on Figure 5.
