FoM
Science investigation and Observational requirement: SI6.2 from Science requirement document.
PE for MBHB used for cosmology
- GREAT 1.0 [0.8 0.9 1.0] : SO6 localization of MBHB sirens
At least 90% of sources with sky localization below 10 deg^2
- OK 8.8 [15 10 5] : SO6 localization of MBHB sirens
Maximum error on sky localization should be below 10 deg^2
- OK 0.923 [0.8 0.9 1.0] : SO6 distance of MBHB sirens
At least 90% sources with luminosity error below 2%
