Writes the decay channels to a file.

Parameters

OutputFile	Path to the output file.
WriteAntiParticles	Whether the decays of antiparticles are to be written to the file as well.

Definition at line 973 of file ThermalParticleSystem.cpp.

void thermalfist::ThermalParticleSystem::WriteTableToFile	(	const std::string &	OutputFile = `""`,
		bool	WriteAntiParticles = `false`
	)

Writes the particle list to file.

Note: this does NOT write the decays. The decays can be written with the WriteDecaysToFile() function.

Parameters

OutputFile	Path to the output file.
WriteAntiParticles	Whether antiparticles are to be written to the file as well.
