Example of a fitted time series. The left y-axis shows the applied weights for each event (Signal over Background: S/B). The x-axis shows the time range in MJD and the vertical blue lines indicate the detection times of the alert events. The orange line shows the best fit temporal signal probability density function, S​_temp, consisting of the sum of k Gaussians, as determined with EM in arbitrary units. The height of each Gaussian is scaled with the number of associated events, n_S, k. S​_temp can reach greater values where many n_S, k contribute, compared to times where a single event has a high S/B value without any close events in time.
