Description

This data set is used to produce Figure 16 of the COMPAS Paper (Team COMPAS et al. 2021).

The file contains the output of 10,000,000 binaries evolved using COMPAS  v02.21.00, using adaptive importance sampling (STROOPWAFEL) , sampling from a metallicity uniform in \(\log(Z) \in [10^{-4},0.03]\). More details can be found in the `Run_Details` group.

Contents
*****************************

  1. COMPAS simulation output:
    The hdf5 file Includes necessary information about the simulated binaries in the following groups:

    BSE_Double_Compact_Objects
    BSE_Common_Envelopes
    BSE_RLOF
    BSE_Supernovae
    BSE_System_Parameters
    Run_    Details

    We point the reader to the documentation at https://compas.science/docs, for information and instructions regarding the contained data.
     
  2. Rate Data
    The hdf5 file contains 1 groups with BBH merger rate data for every BBH with an inspiral time that is smaller than the age of the Universe. This group contains a dataset "DCOmask" which can be used to point from the "DoubleCompactObjects" to the data contained in the respective rates datasets.

    We include the rates for one realization of the metallicity-dependent SFRD as discussed in  the manuscript.
    The metallicity-dependent SFRD used is the phenomenological metallicity-dependent SFRD  as described in Neijssel et al. 2019, this contained in:
    'Rates_mu00.035_muz-0.23_alpha0.0_sigma00.39_sigmaz0.0'

*****************************

The rates were calculated by running ```FastCosmicIntegration.py```  from COMPAS's post-processing tools.
For a more detailed explanation of the workings of COMPAS's post-processing tools, please the docs https://compas.science/docs
