Multimessenger astronomy, enabling pre-localization [1.0 yr]
FoM
Science investigation and Observational requirement: SI2.3 OR2.3a from Science requirement document.
For a MBHBs with source-frame mass in the range \(10^5-10^7\) M\(_\odot\) at \(z = 1\) measurement of: (i) sky localization within \(100\,{\rm deg^2}\) 1 day before merger and (ii) time to coalescence within 4h 2 days before merger.
- GREAT 100.0 [30 50 75] : SO2 Probability to predict merger time
Coalescence time prediction is OK if probability > 50% to get the error in the coalescence time better than 4.0 h 2.0 d before the merger.
- OK 72.58247334415235 [30 50 75] : SO2 Probability of advanced localization
Localization is OK if probability > 50% to get the error in the sky better than 100 deg^2 1.0 d before the merger.
- WARNING 35.84513465257289 [30 50 75] : SO2 Probability of advanced localization
Localization is OK if probability > 50% to get the error in the sky better than 10 deg^2 4.0 h before the merger.
