Fig. 11 shows the expected number of detections of small impactors (bolides) within 10 days of impact during the 4 year
PS1 survey as a function of diameter using the Brown et al. (2002) size-frequency distribution (SFD). The cumulative probability of PS1 detecting a bolide in the 1–10 m size range is 25 ± 15% (the error is determined from the SFD only). In other words, PS1 has 25% probability of detecting another 2008 TC3-like object during its four year survey mission.
