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 :math:`(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.
