B_plus_IDs

B_plus_IDs() // constructor
~B_plus_IDs() // destructor
bool isBplus()
- Parameters
  - counters *counter
  - bool B_plus_TM
- Return
  - True if B+ passes the truth matching, False if not

K_star_IDs

K_star_IDs() // constructor
~K_star_IDs() // destructor
bool isKstar()
- Parameters
  - counters *counter
  - bool K_star_plus_TM
  - bool B_plus_TM
- Return
  - True if K*+ passes the truth matching, False if not. You can also turn off checking the mother particle of K*+ (B+)

K_plus_IDs() // constructor
~K_plus_IDs() // destructor
bool isKplus()
- Parameters
  - counters *counter
  - bool K_plus_TM
  - bool K_star_plus_TM
  - bool B_plus_TM
- Return
  - True if K+ passes the truth matching, False if not. You can also turn on/off checking the mother particle (K*+) an grandmother (B+) via the input parameters

- int pi_zero_TRUEID
- int pi_zero_MOTHER_ID
- int pi_zero_GD_MOTHER_ID

pi_zero_IDs() // constructor
~pi_zero_IDs() // destructor
bool isPi0()
- Parameters
  - counters *counter
  - bool pi_zero_TM
  - bool K_star_plus_TM
  - bool B_plus_TM
  - double pi_zero_resolved_M
  - double B_plus_M
  - TH1D *h_pi0_mismatched_mass
  - TH1D *h_Bplus_mass_pi0mismatched
  - TH1D *h_pi0_resolved_mass
- Return
  - True if pi0 passes the truth matching, False if not. You can also turn on/off checking the mother particle, grandmother and great-grandmother via the input parameters. In the histograms, the masses for (not) matched events are ssaved (that is why you need masses as input).
