Capability to detect a GW190521 like source out to specific horizon distances [4.5 yr]
FoM
Science investigation and Observational requirement: 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.
- GREAT 1064.85547432346 [400 600 800] : Maximum average distance of ~ BH-BH of [84.83168551320219, 65.85979695808804] (solar mass)
Capability to detect a GW190521 like source out to specific horizon distances. FoM is OK if horizon distance above 600 Mpc
Summary
DL tc
We have assumed 4.5 years of observation with 0.89 duty cycle and SNR threshold: 8.0
We have conducted monte-carlo avec 300 trials.
-
for a BH-BH [[84.83168551320219, 65.85979695808804]] (solar mass) system horizon distance = 2617.1909756752107 [Mpc]
-
for a BH-BH [[84.83168551320219, 65.85979695808804]] (solar mass) system maximum mean distance = 1064.85547432346 [Mpc]
