The default particle selection criteria can be found here: [1]. All the selections can be changed in the command line or in the Jana configuration files as followed (p29):

  • Changing the particle time cut:

COMBO_TIMECUT:X_Y Z with X, Y, and Z, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and time cut in ns, respectively

  • Changing the track PID, the timing (treated above), E/P and dE/dx are used
  1. EOVERP:X_Y=Z1_Z2 with X, Y, Z1 and Z2, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and E/P cut in ns, respectively
  2. DEDXCUT:Low_X_Y=Z with X, Y, and Z, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and [FIXME] cuts in [FIXME], respectively
  3. DEDXCUT:High_X_Y=Z with X, Y, and Z, the particle PDG GlueX number, the detector rack number (hex to decimal converter), and a function of p in GeV/c, respectively
  • Changing the meson/baryon, missing mass squared, or missing energy:
  1. Meson/baryon mass:
    1. IMCUT:Low_X=Z
    2. IMCUT:High_X=Z
  2. Missing mass squared:
    1. MM2CUT:Low_Func_X=Z
    2. MM2CUT:High_X=Z
  3. Missing energy:
    1. MISSECUT:Low_Func="function"
    2. MISSECUT:High="value"
