Capability to detect a 10-10 \(M_{\odot}\) BH-BH source out to specific horizon distances [4.5 yr]
FoM
Science investigation and Observational requirement: SI4.2 from Science requirement document.
Compute average distance for tc in range [7-35] years (SNR=8). Report maximum average horizon distance.
- OK 30.89 [10 30 50] : Maximum average distance of BH-BH with masses [10.0, 10.0] \(M_\odot\) (z = 0.007).
Capability to detect a 10-10 \(M_{\odot}\) BH-BH source out to specific horizon distances. FoM is OK if horizon distance above 30 Mpc (z = 0.007)
Summary
DL tc
We have assumed 4.5 years of observation with 0.82 duty cycle and SNR threshold: 7.999999999999999
We have conducted monte-carlo with 300 trials.
-
for a BH-BH [10.0, 10.0] \(M_\odot\) system horizon distance is 55.6 [Mpc] (z = 0.012)
-
for a BH-BH [10.0, 10.0] \(M_\odot\) system maximum mean distance = 30.9 [Mpc] (z = 0.007)
