Capability to detect a GW150914 like source out to specific horizon distances [4.5 yr]
FoM
Science investigation and Observational requirement: SI4.1 SI4.2 OR4.2 from Science requirement document.
Compute average distance for tc in range [7-35] years (SNR=8). Report maximum average horizon distance.
- WARNING 193.31 [100 200 300] : Maximum average distance of BH-BH with masses [38.6, 33.3] \(M_\odot\) (z = 0.042).
Capability to detect a GW150914 like source out to specific horizon distances. FoM is OK if horizon distance above 200 Mpc (z = 0.044)
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 [38.6, 33.3] \(M_\odot\) system horizon distance is 388.2 [Mpc] (z = 0.083)
-
for a BH-BH [38.6, 33.3] \(M_\odot\) system maximum mean distance = 193.3 [Mpc] (z = 0.042)
