<dc:description>This dataset contains the output data of rapid binary population synthesis produced using COMPAS v02.27.05. The details of the initial conditions and setup are described in the "COMPAS_settings_table.pdf" file. We simulate 5 million binaries, at representative metallicities, and store them in HDF5 files, the default format for COMPAS simulations. Each HDF5 file contains the following groups:

‘/BSE_Common_Envelopes’
‘/BSE_Double_Compact_Objects’
‘/BSE_Supernovae’
‘/BSE_System_Parameters’
‘/Run_Details’

For details about the data, such as variable names and attributes, visit the compas.readthedocs.io.
The metallicities chosen for the simulations are:

Z=0.0001: the lowest metallicity accounted for in our stellar evolution tracks;
Z=0.0002: a proxy metallicity for I Zwicky 18;
Z=0.001;
Z=0.0021: a proxy metallicity for the Small Magellanic Cloud;
Z=0.0047: a proxy metallicity for the Large Magellanic Cloud;
Z=0.01;
Z=0.0142: a metallicity representative of the Sun;
Z=0.02: a super-solar metallicity, aka "old Solar";
Z=0.03: the highest metallicity accounted for in our stellar evolution tracks;
U[log10(0.0001), log10(0.03)]: log-uniformly distributed metallicities from the COMPAS metallicities.

This results in 50 million binaries in total.

In addition to the Table in the "COMPAS_settings_table.pdf" file, we include a "Run Details" text file, which contains the setup as specified via COMPAS, for a particular batch of the Z=0.02 simulation. This file contains a representative description of the global properties of all the 10 simulations, but some details, e.g. Clock-Time, vary from batch to batch.
