MBHB with waveform IMRPhenomHM of
- mass = [20000.0, 200000.0] solar mass
- mass ratio in [10, 10] (log uniform),
- redshift = [1.0]
- t0 in [0.10 - 0.95] (uniform)
- chi in [0.00 - 0.00] (uniform))
Conducting monte-carlo over 100 trials, randomizing spins, sky position and orientation
Assuming SNR threshold for detection: 20.0
