If you use (part of) these results in a scientific publication, we would greatly appreciate it if you would cite the source manuscript.
Additionally we point the user to the following Github repository, for plotting notebooks used to produce the Figures in the manuscript:

- COMPAS simulation output:
The hdf5 file Includes necessary information about the simulated binaries in the following groups:
DoubleCompactObjects
Details
SystemParameters
We point the reader to the documentation at https://compas.science/docs, for information and instructions regarding the contained data. - Rate Data
The hdf5 file contains 3 groups with BBH merger rate data for every BBH with an inspiral time that is smaller than the age of the Universe, excluding binaries that experience immediate RLOF after a CE and excluding 'optimistic CE''s.
Each 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 2 realizations of the metallicity-dependent SFRD as discussed in the manuscript.
The default metallicity-dependent SFRD is contained in the group:
'Rates_mu00.025_muz-0.05_alpha-1.77_sigma01.125_sigmaz0.05_zBinned'
For comparison, we have also used 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'
'Rates_mu00.035_muz-0.23_alpha0.0_sigma00.39_sigmaz0.0_zBinned'
