Package <code>AnaDataObjects</code> is part of the SCT [[Event_selection_framework| Event selection framework]]. It contains main objects needed for events analysis.

== class Particle ==
Class <code>Particle</code> describes all particles, including final-state-particles and unstable intermediate particles. It has the following private members:
* int m_pdgCode; /**< PDG code */
* float m_mass; /**< particle (invariant) mass */
* ThreeVector m_p; /**< momentum components */
* ThreeVector m_r; /**< position components */
* ErrMatrix m_errMatrix; /**< error matrix. The order is [px, py, pz, E, x, y, z] */
* std::vector<ParticlePtr> m_daughters; /**< daughter particle pointers */
* EFlavorType m_flavorType; /**< flavor type. */
* EParticleType m_particleType; /**< particle type */
* size_t m_mdstIndex; /**< 0-based index of MDST store array object */
* ExtraInfoMap m_extraInfo; /**< map for user defined info */

It can be constructed with the following constructors:
* Particle(); /** All private members are set to 0. Particle type is set to c_Undefined. */
* Particle(ThreeVector momentum, float mass, int pdgCode, EParticleType particleType=c_Undefined); /** All other private members are set to their default values (0). */
* Particle(const FourVector& momentum, int pdgCode, EParticleType particleType=c_Undefined); /** All other private members are set to their default values (0). */
* Particle(std::vector<ParticlePtr> daughters, int pdgCode); /** Constructor for composite particles. */
* Particle(const sct::MCParticle &mcparticle); /** Constructor from MC Particle of podio tree */
* Particle(const sct::Particle &particle, int pdg, size_t partIndex); /** Constructor from MC Particle of podio tree */
