#include <gparticle_reader.h>

Data Fields
std::string	name
	Particle name when known, otherwise a source-format identifier such as the numeric pid.

int	pid = 0
	PDG id or source particle id.

int	type = 1
	Source generator type. Lund `type` == 1 means propagated in Geant4.

int	multiplicity = 1
	Number of copies represented by this record.

double	p = 0
	Momentum magnitude in GEMC internal units.

double	theta = 0
	Polar angle in GEMC internal angular units.

double	phi = 0
	Azimuthal angle in GEMC internal angular units.

double	vx = 0
	Vertex x coordinate in GEMC internal length units.

double	vy = 0
	Vertex y coordinate in GEMC internal length units.

double	vz = 0
	Vertex z coordinate in GEMC internal length units.

Detailed Description

A record is a serialization-friendly description of a generated particle. Unlike Gparticle, it does not require that the particle name or id can be resolved by G4ParticleTable. This allows output banks to preserve all particles found in an input file, including bookkeeping or event-generator rows that are not propagated in Geant4.

The kinematic and vertex values are stored after the reader's unit conversion. For Lund input, type preserves the Lund particle type column; type == 1 identifies rows propagated by Geant4.
