Description

POSYDON (v2) binary population synthesis populations for four supernova prescriptions: Sukhbold_16_engine_N20, Sukhbold_16_engine_W20, Patton_Sukhbold20_engine_N20, and Patton_Sukhbold20_engine_W20. Each prescription was run at eight metallicities: Z/Z☉= 0.0001, 0.001, 0.01, 0.1, 0.2, 0.45, 1, and 2.

Population files are named ___Zsun_population.h5. Files without a prescription prefix correspond to the Patton_Sukhbold20_engine_N20 model; files for the other three prescriptions include the corresponding prescription name as a prefix. Each file is a pandas HDFStore containing the POSYDON history and oneline tables for 10^6)binaries.

All populations assume burst star formation, a Kroupa (2001) primary IMF, a flat mass-ratio distribution, and the Sana et al. (2012) orbital-period distribution. The corresponding __population_params.ini file contains the exact POSYDON configuration used for each supernova prescription.
