DINGO-BNS estimates all BNS parameters in just 1 s (orange, 10.8% sample efficiency), reproducing LVK results 5 (black, 0.1% typical efficiency) three orders of magnitude faster than existing methods 17 , 33 , 39 . DINGO-BNS can also analyse partial data before the merger occurs (teal, 78.9% efficiency). Fast analysis results are crucial for directing electromagnetic searches for prompt, or even precursor, signals. Note that GW170817 overlapped with a loud glitch, which could explain why the true sky position lies in the tail of the pre-merger distribution.
