MBHB with waveform IMRPhenomHM of

  • mass = [500000.0, 1000000.0, 5000000.0, 10000000.0] solar mass
  • mass ratio in [1, 10] (log uniform),
  • redshift = [2]
  • t0 in [0.10 - 0.95] (uniform)
  • chi in [0.00 - 1.00] (uniform))

Conducting monte-carlo over 1000 trials, randomizing spins, sky position and orientation

Assuming SNR threshold for detection: 10.0

For derived parameters (dz/z, dMf/Mf), random samples are drawn from the inverse Fisher, derived quantities are computed and we extract their standard deviation and mean.

For the following waveform parameters (dMc/Mc, dDL/DL, dq/q), we use a log10 parameterization.

We report observer frame errors.
