Particle Properties
The particle properties file is optional. Provide the path using the particle_properties_input_file if you are not using the Calculation Engine, and enable the output_particle_properties option in the config file to generate its output.
The only requirements is that the first 7 columns must be the same as the EoS file, namely \((T, \mu_B, \mu_S, \mu_Q, n_B, n_S, n_Q)\). In this way, the file can be interpolated for the beta-equilibrated EoS. Further columns can be added to have your own model information, such as particle densities, chemical potentials, masses, meson field values, baryon number, etc.
For the particle properties file associated to the Leptonic EoS, the format follows the Lepton module standard:
