Comparison between the NEOForCE impact monitoring system and Sentry-II. This figure summarizes the results from Tables 1–5. We show only impact probabilities larger than 10⁻⁹. A point located on the horizontal line at P_NASA = 10⁻⁹ indicates a potential impact identified by NEOForCE but not detected by Sentry-II. Conversely, a point on the vertical line indicates an impact detected by Sentry-II but not found by NEOForCE.
