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.

- OK 618.0 [400 600 800] : Maximum average distance of BH-BH with masses [84.8, 65.9] \(M_\odot\) (z = 0.128).

Capability to detect a GW190521 like source out to specific horizon distances. FoM is OK if horizon distance above 600 Mpc (z = 0.124)

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 [84.8, 65.9] \(M_\odot\) system horizon distance is 1414.7 [Mpc] (z = 0.269)

  • for a BH-BH [84.8, 65.9] \(M_\odot\) system maximum mean distance = 618.0 [Mpc] (z = 0.128)
