Frequency of number of candidates per day (24 hour period) within half a day, one day and two days of the current predicted peak (in black, red and blue respectively). These measurements are made only for days where ZTF alerts were delivered. The mean number of candidates per day for each selection is denoted by the dashed vertical line. There are a mean of $\overline{N}=2.08\pm 0.07$ candidates within 0.5 days of the peak, $\overline{N}=4.2\pm 0.1$ per night within one day of the predicted peak, and $\overline{N}=8.3\pm 0.2$ within two days of the predicted peak.
